The short answer: the TST 507 Series with four cap sensors is the best tire pressure monitoring system for RVs overall, because it pairs accurate readings with a three-year warranty, replaceable sensor batteries and expandability to a tow vehicle plus multiple trailers. The TireMinder i10 is the best value for owners who want a color screen and a signal booster in the same box, and the Masoll M13 is the cheapest sensible way to start monitoring.
RV tires fail quietly. A rear dual on a fifth wheel can sit four pounds under its placard cold pressure for weeks and still look perfectly normal from the cab, and that slow leak is the one that shreds a sidewall on the interstate. Sensors on the valve stem turn that invisible drift into a number and an alarm.
We spent weeks reading the owner data behind these systems, comparing alarm logic, PSI range, sensor count, signal distance and warranty terms, and reading what owners say on iRV2, The RV Forum and r/RVLiving. The category splits into two families that resolve very differently, and that fork decides most of your purchase.
The word tire pressure monitoring system is unwieldy, so we use TPMS throughout. The primary keyword for this page is best tire pressure monitoring systems for RVs, and everything below is chosen to serve that decision rather than to fill a list.

1. TST 507 Series TPMS: Best Overall RV Tire Pressure Monitor
TST 507 Series TPMS – RV Tire Pressure Monitoring System with 4 Cap Sensors & Color Display Monitor for Travel Trailers, Campers and Motorhomes
Alerts: low, high, fast leak, high temperature
3.5-inch color display, rechargeable battery
Sensor batteries: replaceable CR2032
Warranty: 3 years
Pros
- Replaceable CR2032 sensor batteries with low-battery alerts
- Expandable to a tow vehicle plus up to four towed units
- Auto-lock keeps the problem tire on screen
- Suction cup and rubber dash mounts included
- USA-based live support
Cons
- Cap sensors must be removed to inflate or check tires
- Programming multiple axles and spares takes some learning
This is the kit that RV owners mention most often when they argue about reliability, and the reason is battery serviceability. The sensors take a CR2032 coin cell you can swap yourself, so a dead sensor costs a few dollars instead of a trip to a dealer and a new transmitter.
Owner threads on iRV2, The RV Forum and r/RVLiving repeatedly describe three-plus years on the original sensor batteries, which is a durability claim almost no competing kit can make. Those same forums describe owners moving sensors between wheel positions after a rotation and re-pairing positions in the menu without re-pairing the sensors themselves.
The alerts cover the four conditions that actually matter on a towable: low pressure, high pressure, fast leak and high temperature. When one tire trips a threshold, the display locks onto that tire rather than flashing back to the overview, which saves you the mental work of finding it in a list of ten.
The kit ships with a monitor, four cap sensors, a power cable, mounting hardware and a user manual, and the display uses a rechargeable battery with a Micro-USB charger. Expect to spend real time in the pairing menu the first afternoon, because mapping tire positions across a tandem axle takes a few attempts.
What the TST 507 does well on a real rig
Expandability is the deciding factor for anyone with a truck, a fifth wheel and a toad in the yard. The system scales to a tow vehicle plus up to four towed units, which means one purchase can cover the trailer, the truck and a car being towed behind it.
The three-year warranty and USA-based live support also carry weight when a sensor drops out mid-trip in a state you have never visited. That kind of backing is a genuine difference from generic kits with no support line.
Where the TST 507 falls short
Cap sensors have one unavoidable drawback: you pull them off to add air. On a gravel road, at a nitrogen fill station or in a dark truck stop lot, that is a small annoyance that never gets old, and it is the argument flow-through versions exist to solve.
The programming step is also fiddly. If you have never paired a multi-axle system, budget an hour for the first setup and keep the manual nearby, because the learn sequence is the part that causes the most returns in this category.
2. TireMinder i10: Best Value RV TPMS With a Booster in the Box
TireMinder i10 RV TPMS with 4 Transmitters, Black
Display: 3.15-inch color LCD
Range: 0-199 PSI, up to 40 tires
Scan interval: 6 seconds
Includes Rhino signal booster
Pros
- Booster included in the box
- Up to 40 tires supported
- 0-199 PSI suits high-pressure truck tires
- Plus or minus 1 PSI accuracy
- Simultaneous PSI and temperature on one screen
Cons
- Only four transmitters included so bigger trailers need extras
- Slim monitor unit is small for dash viewing
The i10 solves the problem that trips up most owners on long rigs: signal. A Rhino booster is in the box, and at 0-199 PSI the system handles the high-pressure truck tires that many RV-specific kits cannot read at all.
That range matters more than it sounds. A pickup running 100-plus PSI on a heavy tow package will simply fall outside the 0-87 or 0-99 PSI ceiling of several budget systems, and a monitor that cannot read your truck tires is a monitor with a hole in it.
Scan speed is the quiet strength here. A six-second interval across six alarm conditions catches a slow leak and a blowout on the same system, and the screen shows PSI and temperature together so you can watch a tire warm up before it deflates.
Because the transmitters are replaceable and not proprietary, adding sensors for a tandem axle or a spare is straightforward. Eight lithium metal batteries ship in the box for the sensors, and the display runs on its own internal power.
Where the i10 earns its value ranking
Including the booster is the single biggest reason to pick this kit over a cheaper four-sensor system. Signal loss on rigs over 35 to 40 feet is the most common complaint in owner forums, and buying the booster separately later usually costs more than the difference between kits.
Support and expandability also rate well. Owners running a truck, trailer and toad report filling all tires on one screen without switching displays, which is the layout most of them asked for.
Where the i10 is the wrong buy
Four transmitters is a modest starting count. A tandem-axle trailer plus truck and toad will need considerably more, and each extra sensor adds to the install cost you were hoping to avoid.
The monitor itself is slim, and reviewers who mount it low on the dash sometimes find the viewing angle tight in direct sun. The included mounts help, but check where you plan to put it before you commit.
3. GUTA GT30: Best for Multi-Axle Rigs With a Lot of Tires
GUTA GT30 Trailer Tire Pressure Monitoring System, RV TPMS with 10 Sensors
Ten sensors included
Up to 188 PSI and 185F
Screen shows 10 tires per page
46 tires viewable in total
Pros
- Handles high pressure and high temperature ranges
- Ten tires shown per page with front and rear auto-switching
- Wireless pre-programming before installation
- CR2032 sensor batteries rated up to four years
Cons
- Manufacturer recommends metal valve stems
- A separate signal booster is needed for maximum range
Ten sensors in one box removes the most common first-week regret in this category, which is running out of sensors with a tandem axle still half covered. For owners of a dual-axle trailer plus a truck, this is the configuration that fits without a second order.
The GT30 is also the more serious option for heat. A 188 PSI ceiling and a 185F upper temperature reading cover load-rated RV and trailer tires that lighter systems top out below, and high temperature is the precursor warning you want before a sidewall lets go.
Wireless sensor pre-programming is an underrated feature here. You configure each sensor before it ever goes on a wheel, which removes the tap-each-sensor-in-order step that catches new owners out on other systems.
The display fits up to ten tires per page and can view up to 46 across front and rear sections with auto-switching, so a Class A with a tag axle or a toad still fits the layout. Six alert types include missing signal and low battery, which are exactly the two faults owners never see coming.
Why multi-axle owners pick this one
Sensor count is the deciding factor when you have a tag axle, dual rear wheels on a Class C, or a fifth wheel with a truck in front of it. Ten sensors covers the common combinations without arithmetic, and the page layout keeps all readings visible rather than forcing you to scroll.
Owner reviews rate the high-pressure handling highly, and the 73 percent five-star share reflects solid value for the tire count you get. Sensor batteries are rated for up to four years, which pushes replacement far down the list of things to think about.
What to know before you buy
The manufacturer recommends metal valve stems, and rubber stems are not recommended for sensor stability. That is a real constraint on older trailers, and converting stems is a separate job with its own parts list.
Expect to add a signal booster separately if your rig is long. Rated range is not the same as usable range once a trailer is behind a truck, metal frame and several feet of gravel road, and the booster is the fix that owners with 40-foot fifth wheels usually land on.
4. Masoll M13: Most Versatile With Auto Calibration
Masoll M13 Tire Pressure Monitoring System, RV/Trailer TPMS with 4 Sensors
Four sensors and an LCD monitor
0-87 PSI at about 1.5 PSI accuracy
Solar charging with overheat protection
Warranty: 1 year monitor, 6 months sensors
Pros
- Auto-calibration sets thresholds with no manual setup
- Solar panel with overheat and overcharge protection
- Color LCD auto-adjusts brightness day and night
- Lowest entry cost with a four-sensor kit
Cons
- Booster recommended for trailers longer than 38 feet
- Shorter warranty than premium competitors
The feature that separates the M13 from other entry kits is auto calibration. After you inflate to the placard pressure, the system captures that as a reference and sets its alarm bands at plus 25 percent and minus 15 percent on its own, which removes the most common false-alarm complaint in this category.
Manual threshold setup is where a lot of owners lose patience. They set alerts too close to running pressure, the monitor chirps on every hot afternoon, and within a month they stop looking at the screen.
Accuracy sits at about 1.5 PSI across a 0-87 PSI range, which is tighter than the plus or minus 3 PSI tolerance of several kits in the same bracket. For RV and travel trailer pressures in the 30 to 60 PSI range, that margin is comfortable.
Solar charging with overheat and overcharge protection makes it a good dry-camping companion, and the display has an anti-reflective coating with auto brightness so it stays readable at night without a USB cord.
Where the M13 makes sense
This is the kit for a single-axle or tandem trailer under about 30 feet where you want alerts without deep menu work. Four sensors cover a small trailer, and the set is the least expensive way to get all-tire readings on a dash.
Owners consistently rate value and display legibility positively, and the review base is large enough to trust. If the rig is a trailer rather than a motorhome, the absence of a phone screen and the calm auto-calibrated alarms are genuine wins.
Where it falls short
The 38-foot guidance is a hard limit worth respecting. Beyond that, owner feedback points to range limits on the rear tires, and adding a booster moves you into a price band where other kits include one.
Warranty is the other soft spot: one year on the monitor and six months on the sensors. That is a meaningful gap against three-year coverage, and it matters if a sensor fails in month eight.
5. TST 507 Flow-Through Version: Best for Nitrogen Fills and Gravel Roads
TST 507 Series TPMS – RV Tire Pressure Monitoring System with 4 Flow Thru Sensors & Color Display Monitor for Travel Trailers, Campers and Motorhomes (Metal Valve Stems Required for Flow Thru)
Four flow-through sensors
1-218 PSI range, 105 foot sensing distance
Accuracy about +1.5 PSI
Warranty: 3 years
Pros
- Inflate and check pressure without removing sensors
- 1-218 PSI range covers heavy truck and trailer tires
- Three-year warranty with USA-based support
- Expandable to a tow vehicle plus four towed units
Cons
- Color screen is hard to read in direct daylight
- Each tire appears only as the display cycles
- Flow-through sensors require metal valve stems
- Proximity sensor on dually rear wheels is vulnerable to curb strikes
This is the same proven display and receiver as our top pick, fitted with flow-through sensors instead of caps. That single change removes the most irritating routine in RV tire care, because you can top off pressure without pulling four transmitters off four valve stems.
Flow-through matters most for nitrogen fills and for rigs that spend time on gravel. Cap sensors mean kneeling at a wheel with a wrench every time you check pressure, and owners who run nitrogen in their tires report that as the deciding factor.
The measurement numbers are strong: about plus 1.5 PSI accuracy across a 1-218 PSI range with 105-foot sensing distance. The upper end of that range covers high-pressure truck tires that many RV-focused systems cannot read.
Everything else matches the cap version, including the rechargeable 3.5-inch color display, suction cup and dash mounts, replaceable CR2032 batteries, the repeater, the magnetic mount and the three-year warranty.
Who should pay for flow-through
If your tires carry nitrogen or you add air often, the flow-through design pays for itself in convenience alone. You still get the same alerts, the same expandability and the same support as the cap kit, and the inflation step becomes a five-second job.
Accuracy at plus 1.5 PSI is the figure owners cite most, and the 72 percent five-star share reflects that readings hold up against a mechanical gauge rather than drifting a few pounds loose.
What the extra hardware demands
Flow-through sensors require metal valve stems, and installation has to be done carefully to avoid leaks. A rubber stem is not a valid mount for this design, so older trailers need a stem conversion first.
Two display issues come up repeatedly. The color screen is hard to read in direct daylight, and each tire only refreshes as the display cycles, roughly every 30 seconds, so it is less immediate than a system that shows all readings at once.
6. GUTA GT20: Best for High-Pressure Truck Tires and Zero Setup
GUTA GT20 Trailer Tire Pressure Monitoring System, TPMS with 10 Sensors
Ten sensors, 0-188 PSI
Working range -40F to 221F
Up to 100 feet with booster
Large color LCD, 15-hour internal battery
Pros
- Wide pressure and temperature envelope for heavy tow packages
- Sensors ship pre-labeled and factory paired
- Adjustable display orientation and backlight
- Up to 24 tires with six real-time alert modes
Cons
- Booster is not included with the four-sensor kit
- Metal valve stems are recommended over rubber
The GT20 is the pick for owners whose biggest worry is the front tires, not the trailer. A 0-188 PSI range and a -40F to 221F temperature envelope cover heavy tow packages and cold-weather starts, which is a wider window than most RV-specific kits offer.
Pre-labeled, factory-paired sensors are the sleeper feature. Because nothing needs to be learned or tapped into place, installation drops to screwing on ten transmitters and mounting the display, which removes the most common setup stumbling block.
Up to 100 feet of boosted connectivity is useful for a long combination, and up to 24 tires means the system can cover a Class A with a toad without a second receiver. Units switch between PSI and BAR and between Celsius and Fahrenheit, with custom thresholds.
The color LCD has adjustable backlight and switchable orientation, and a 15-hour internal battery keeps it alive through a drive when the charging cable is out of reach. That internal reserve is genuinely useful for boondocking setups.
Where it earns a spot on the list
Ten sensors plus 24-tire capacity covers truck, trailer, spare and toad in one system, and the wide temperature ceiling makes it comfortable in genuinely cold climates where narrower sensors drift.
Reviewers like the wide pressure and temperature range and the turn-key pairing. A 70 percent five-star share is solid for a kit that has been on sale for a couple of years.
What to weigh against the price
The booster is not included with the smaller four-sensor configuration, so budget for range if your rig is long. The 100-foot figure is the boosted number, and real-world coverage on a metal-framed trailer is shorter.
Like the other GUTA kits, the manufacturer recommends metal valve stems and does not recommend rubber. On a trailer with older rubber stems, that is a part to plan for before installation day.
7. LETOURWM M12-3: Six Sensors and IP67 Sealing at the Entry Level
RV Tire Pressure Monitoring System -TPMS Tire Pressure Monitor with 6 Sensors,M12-3 TPMS Solar Charge & USB Color LCD Display, 0-9.9BAR/144PSI Range, 6 Alarm Modes for RV/Trailer/Truck IP67
Six sensors, 0-144 PSI
65 foot sensing range
IP67 dust and water resistance
Solar and USB charging
Pros
- Six sensors cover a tandem trailer in one box
- Six alarm modes including slow and rapid leak
- Voice broadcast alerts with auto-brightness HD LCD
- Includes jam nuts and a small wrench
Cons
- No clear connected or disconnected indicator
- Sensors are sensitive to heavy rain and may need resets
- Instructions are hard to follow and sensor numbering is unintuitive
Six sensors at the entry level is the configuration most trailer owners actually need. A tandem-axle travel trailer has six tires to cover, and this is one of the few low-cost kits that ships enough transmitters to cover them without a follow-up order.
The 0-144 PSI range is wider than most kits at this tier and comfortably covers typical RV trailer pressures with headroom. IP67 dust and water resistance also matters more than it sounds on a rig that lives outside in rain and road spray.
Voice broadcast alerts are unusual at this level and genuinely useful, since you do not have to look down at the screen. Solar and USB charging keeps the monitor running on long trips, and auto brightness handles the day and night change.
Six alarm modes cover high and low pressure, high temperature, rapid and slow leaks, sensor failure and low battery. Slow-leak detection is the mode that earns its keep on a trailer that sits for weeks between trips.
Who this kit works for
A tandem travel trailer owner who wants coverage now, at the lowest entry cost of anything on this list, gets the most from it. Installation hardware including jam nuts and a small wrench is in the box, so the physical install is not the obstacle.
A 61 percent five-star share reflects strong perceived value and an easy install. The display is large and the reading layout is clear, which is more than a lot of kits in this bracket offer.
What to be careful about
There is no clear connected or disconnected indicator, so a stale reading can look like a live one. That is the single most important thing to know about this kit, because it affects how much you trust the screen.
Owners also report sensor sensitivity to heavy rain, with occasional resets needed, and instructions that are hard to follow with unintuitive sensor numbering. If you are not comfortable mapping positions, plan for a slower first setup.
8. GUTA GT80: Highest-Rated Kit With a Vertical Touchscreen
GUTA GT80 RV Tire Pressure Monitoring System, 10 Flow-Thru Sensors TPMS
Ten flow-through sensors
0-188 PSI real-time monitoring
Vertical full-color touchscreen
Up to 34 tires, 22 shown per page
Pros
- Highest average rating in this group at 4.5
- Flow-through sensors so tires can be topped off in place
- Pre-labeled factory-paired sensors with full hardware kit
- Booster extends range to 164 feet
Cons
- Inner rear tires can drop out briefly on rough roads
- Flow-through sensors require metal valve stems
The GT80 carries the highest average rating in this roundup, and the reason is that it combines the two things owners argue about most: flow-through convenience and a display you can actually operate quickly.
A vertical full-color touchscreen with touch and sound feedback is a departure from the small landscape screens most TPMS units use. It runs 10 sensors per page with front and rear auto-switching, and up to 34 tires are monitored in total, with 22 shown per page.
Because the sensors are pre-labeled and factory paired, there is no learning sequence. The box includes jam nuts, o-rings and a wrench, and reviewers single out the 29-page documentation as unusually thorough for a kit in this price bracket.
Range is handled well, with the booster extending coverage to 164 feet. A 10-minute auto power saving mode and firmware updates keep the unit current, and vibration wake-up lets it read a stationary spare tire.
Where the GT80 stands out
Flow-through plus a big screen is the combination owners with a lot of tires tend to converge on. Topping off a fifth wheel with ten flow-through sensors and no tools at each wheel is a materially different morning than the same job with caps.
With only 4 percent one-star reviews, the consistency of the rating is notable. Owners point to the portrait touchscreen, the flow-through convenience and the documentation as the reasons it holds its score.
What gives us pause
Inner rear tires can drop out briefly on rough roads before recovering. If you run a lot of washboard gravel, that flicker is the thing you will notice first.
Flow-through sensors require metal valve stems, so this is not a drop-in on a trailer with rubber stems. The review base is also the second smallest here, which means long-term durability data is still building.
9. Lippert Tire Linc PRO: Best for CarPlay and Android Auto
Lippert Tire LINC PRO RV Tire Pressure/Temperature Monitoring System (TPMS) 4-Tire Bundle with External Stem Sensors, Repeater, and Dock #2024115889
Four external stem sensors
Displays through Apple CarPlay and Android Auto
Bundle includes repeater and dock
Reporting slows while parked to save battery
Pros
- Readings appear on the factory dash you already use
- Scales easily with sensors for extra tires or a toad
- Parked mode cuts reporting frequency to conserve battery
- Backed by an established RV manufacturer
Cons
- Relies on a phone or head unit instead of a dedicated screen
- Newest listing with the smallest long-term review base
This is the answer to the iPhone question. Tire Linc PRO sends live pressure and temperature to Apple CarPlay or Android Auto, so readings sit inside the screen your rig already has instead of on a second device taped to the dash.
That approach trades a dedicated monitor for integration. If you dislike extra hardware, or your tow vehicle has a head unit that already handles the truck tires, putting the trailer data in the same place is a cleaner layout.
The bundle includes external stem sensors, a repeater and a dock, and it scales with additional sensors when you need coverage for more tires or a towed vehicle. External stems are also easier on rubber valve stems than a cap that has to be removed for every fill.
An energy-saving mode reduces reporting frequency while parked, which protects sensor life on rigs that sit for months. The 4-tire version is the base, with 2-tire and 6-tire kits also offered.
Why an OEM system is worth a look
Lippert builds RV hardware and supports it through an existing service network, and owners who bought the trailer new already have a relationship with the brand. For a rig that may arrive with a factory system, matching that ecosystem removes a support headache.
If your trailer already carries an OEM monitor, the honest answer is that you can add an aftermarket system alongside it, but you will be running two devices and two alert systems. Adding more sensors to the existing one is usually less to manage.
Where it is not the right call
Dependence on a phone or head unit means the display goes away when the device does. For a boondocking trip with no reliable power or signal for your phone, a self-contained monitor with its own solar charging is the safer bet.
It is also the newest listing here, with 61 reviews and a 59 percent five-star share. There is not yet the multi-year owner history that the established kits have, and that history is exactly what you want when deciding whether to trust the readings.
10. Tymate TM2: Most Reviewed Budget System for Ten Tires
Tymate TM2 RV Tire Pressure Monitoring System, TPMS Set of 4 Sensors
Four sensors, up to 10 tires monitored
0-87 PSI range, plus or minus 3 PSI accuracy
Solar, USB and cigarette lighter charging
Five alarm modes
Pros
- Largest review base of any kit here at 4592 ratings
- Monitors up to 10 tires including spares
- Five alarm modes covering fast leak and high temperature
- Color-coded status screen with auto backlight
- Solar charging suits boondocking
Cons
- Plus or minus 3 PSI tolerance is looser than premium systems
- Cigarette lighter charging adapter not included
- Metal valve stems recommended for stability
The TM2 is the consensus budget pick on owner forums, and the reason is the review volume. With 4592 ratings it has a longer public track record than anything else in this roundup, so its strengths and weaknesses are well documented rather than discovered after you buy.
For coverage, a four-sensor kit that monitors up to 10 tires is unusual. You pay for four transmitters but the receiver will track ten positions, which is how owners stretch a small kit across a trailer, a spare and part of a truck.
Five alarm modes cover fast leak, high and low pressure, high temperature and low sensor voltage. Alert values are user-set within a plus 25 percent to minus 15 percent band of your reference pressure, and auto backlight with status-based screen colors means you can read the state of the rig at a glance.
Charging is unusually flexible: solar, USB and cigarette lighter options, with an auto-sleep power saving mode. Two-year manufacturer coverage is longer than the entry kits in this group, and the sensors use replaceable CR1632 batteries.
Who this kit suits
Smaller trailer owners who want ten tire positions and a broad alarm set without a premium system will find the most here. The auto-calibration-style alert band means the thresholds behave predictably once you set a reference pressure.
Because the batteries are replaceable and the parts are ordinary, maintenance is straightforward. A four-sensor or six-sensor variant is also available, which makes it easy to size the kit to the rig.
What the accuracy tolerance costs you
Plus or minus 3 PSI is looser than the plus or minus 1 PSI of the TireMinder or the plus 1.5 PSI of the TST kits. On a 50 PSI tire that is a meaningful band, and it is the main reason this lands at the bottom of our ranking despite the huge review base.
Owners also report installation-hardware friction, and the manufacturer recommends metal valve stems for sensor stability. The cigarette lighter adapter is not included, so budget for that cable if you want that charging option.
RV TPMS Buying Guide: Sensor Type, Sensor Count and Signal Range
Most wrong purchases in this category come down to four decisions: cap or flow-through, how many sensors, how far the signal has to reach, and where the readings appear. Get those right and the brand matters much less.
Cap sensors or flow-through sensors?
Cap sensors screw on over the valve stem in place of the dust cap. They are cheaper, simpler and the majority of owner reports favor them for reliability, which is why our top pick uses them.
Flow-through sensors pass air through, so you can add air or nitrogen without pulling a sensor off. They cost more, they need metal valve stems, and installation has to be done carefully to avoid leaks. They are worth it if you fill often or run nitrogen.
One community complaint worth knowing: multiple owners advise against the TST flow-through sensors in favour of the standard cap sensors, citing reliability concerns with the flow-through design specifically.
How many sensors does your RV need?
Count every tire you want a reading from, including the spare if you want it monitored. A single-axle travel trailer needs three, a tandem-axle trailer needs six, and a truck plus tandem trailer plus toad is where ten-sensor kits stop being excessive.
Buy the tire count that matches the configuration you own now, and prefer a system with headroom if you plan to add a toad or swap trailers. Sensor add-on cost is the number that quietly inflates on a rig with eight monitored tires.
When do you need a signal booster?
Rated range is a laboratory figure. Expect roughly 60 to 70 percent of it in a real combination, because the trailer sits behind a truck, a metal frame and a length of road surface that absorbs signal.
Under 30 feet, you can usually run without help. Between 30 and 40 feet, plan on a booster if you want dependable readings on the rear duals. Beyond 40 feet, treat a booster as required rather than optional.
Two kits on this list include one in the box: the TireMinder i10 with its Rhino booster, and the TST 507 kits with a repeater. Buying it with the system is cheaper than adding it later.
Display unit or smartphone app?
A dedicated monitor keeps working with no phone, no signal and no cable, which matters when boondocking. A phone app, as on the Lippert Tire Linc PRO, integrates cleanly with CarPlay and Android Auto but depends on your device staying powered and connected.
For most owners who already run a second screen on the dash, a standalone solar-charged monitor is the more dependable option. For owners who hate extra hardware, the app route is a legitimate answer to the iPhone question.
Setting alert thresholds without false alarms
Take your cold inflation pressure from the tire placard on the driver door or the trailer frame, not from the sidewall maximum. The sidewall number is a maximum, not a target.
Owners on iRV2 and The RV Forum generally set alerts about 5 PSI above recommended cold pressure, so a drop to standard pressure triggers a warning. That headroom kills the constant false alarms that come from thresholds set too close to running pressure.
Systems with auto calibration, like the Masoll M13, set the band for you at plus 25 percent and minus 15 percent of your reference pressure, which is why they tend to stay quiet in normal use.
If your rig already has a factory TPMS
Newer Lippert trailers ship with Tire Linc or Tire Linc PRO, and the difference is mainly how readings are displayed: the standard system uses its own hardware, while the PRO version routes pressure and temperature through Apple CarPlay or Android Auto.
Aftermarket systems are as good as OEM for pressure and temperature accuracy, and they are better in one respect: you can choose sensor type, tire count and display. You can also run an aftermarket kit alongside a factory system, since the frequencies do not conflict, but two alert systems is one more thing to manage.
Adding sensors to the system already in your wall is usually the cleaner path, provided the tire count fits. Beyond that ceiling, an aftermarket kit is a straightforward swap.
One last practical note that rarely makes a buying guide: sensors are small metal cylinders on exposed valve stems, and theft at campgrounds is a real concern. Locking valve caps cost very little and are worth adding to any system with external cap sensors.
Frequently Asked Questions
What is the best tire pressure monitoring system for a 5th wheel RV?
For most fifth wheel owners the TST 507 Series with cap sensors is the best overall choice, because it holds a 4.4 rating, runs on replaceable CR2032 sensor batteries and scales from a tow vehicle to four towed units. Choose the flow-through variant instead if you run nitrogen fills or add air frequently, and add a booster for fifth wheels over 40 feet.
Is there an RV tire pressure monitoring system that can be used with an iPhone?
Yes. The Lippert Tire Linc PRO sends live pressure and temperature to Apple CarPlay and Android Auto, so readings appear on your vehicle display instead of a separate monitor. A dedicated solar-charged monitor is still more dependable when you boondock with no power for your phone.
How many TPMS sensors does an RV need?
Count the tires you want readings from. A single-axle travel trailer needs three sensors, a tandem-axle trailer needs six, a fifth wheel with a truck and toad can reach ten, and adding a spare takes it higher. Buy the count that matches your rig, leaving headroom if you plan to tow another vehicle.
What PSI should I set RV tire pressure alerts at?
Use the cold inflation pressure printed on your tire placard, not the sidewall maximum. Many owners set the alert about 5 PSI above that recommended cold pressure so a drop to standard pressure triggers a warning. This spacing also prevents the constant false alarms that come from thresholds set too close to running pressure.
Do I need a signal booster for my RV?
Under about 30 feet you can usually manage without one. Between 30 and 40 feet, a booster is worth adding to keep readings on the rear duals dependable, and beyond 40 feet treat it as required. Expect roughly 60 to 70 percent of rated range in a real combination, and note that the TireMinder i10 and both TST 507 kits include one.
How long do RV TPMS sensor batteries last?
It depends on the design and how often the system reports. TST 507 sensors use replaceable CR2032 cells, and multiple owners report three-plus years on the original batteries, while GUTA sensors are rated up to four years. Systems with slow or reduced reporting while parked, such as the Lippert Tire Linc PRO, stretch battery life further.
Final Verdict: Which RV Tire Pressure Monitor Should You Buy?
The best tire pressure monitoring systems for RVs split by rig length, tire count and filling method, but the TST 507 Series with cap sensors is the pick we would put in most towable RVs. It combines replaceable sensor batteries, three-year warranty coverage and expansion across a truck, trailer and toad, and owner reports of multi-year battery life are what the cheaper kits cannot match.
Pick the TireMinder i10 if you want a booster in the box and a PSI ceiling high enough for your truck tires. Pick the Masoll M13 if the rig is under 30 feet and you want alerts that never cry wolf.
Whichever you choose, install it, set thresholds from your tire placard, and add locking valve caps. You can use the buttons below to check the current details for each kit.
