TymateBig color LCD, 6 alarms
9.2OUT OF 10
Build Quality9.3
Ease of Use9.4
Signal Range9.0
Owner Verdict9.1
This is the clearest dashboard TPMS for RV owners who want simplicity without sacrificing alarm coverage. The TM7 packs a big color LCD that shows pressure and temperature for up to five tires at once. You get six distinct alarm modes covering rapid pressure loss, high temperature, and slow leaks. That matters when you are hauling a heavy trailer and cannot afford a blowout on the highway.
Installation takes about 15 minutes. You screw the four external sensors onto your valve stems and plug the display into a 12V socket. The 0-144 PSI range covers everything from a passenger car to a loaded RV. Verified buyer feedback consistently praises the screen readability in direct sunlight, which is a common pain point with cheaper TPMS units.
Flaws but not dealbreakers. The TM7 lacks solar charging, so you need to keep it plugged in. Some owners wish the display came with a longer power cable for flexible dashboard placement. It also does not support flow-through sensors, meaning you have to remove the sensor each time you add air.
Need a version that charges without a cord? The
Tymate TM2 further down adds solar and USB charging while keeping the same alarm modes.
⚠Compatibility: The sensors work on valve stems with a standard 11.33mm thread. Check that your RV or trailer stems are not recessed or angled before buying.

Build Quality9.0
Ease of Use9.2
Signal Range8.8
Owner Verdict9.0
The TM2 is the right choice if you need to keep an eye on more than a handful of tires without worrying about battery life. It supports up to ten tires across your tow vehicle and trailer, and the display recharges via both solar and USB. That means you can leave it on the dashboard and rarely think about plugging it in. The color LCD shows pressure and temperature for each tire in a single glance.
Owner reports consistently mention how easy the pairing process is. You screw on the four included sensors, and the display auto-detects them within a minute. The 0-144 PSI range covers everything from a sedan to a Class A motorhome. The six alarm modes include alerts for slow leaks, rapid pressure drops, and high temperature, which is critical for long mountain grades.
Flaws but not dealbreakers. A handful of buyers noted the solar panel needs direct sunlight to keep the display topped up. On cloudy days or in a shaded cab, you will need to use the USB cable. The external sensors are also standard thread, so you cannot inflate through them.
If topping up without removing sensors matters more to you, the
Tymate TM12 with flow-thru sensors solves that completely.
⚠Sizing: The TM2 display measures roughly 3 inches by 2 inches. Check that your dashboard has a flat spot with enough sunlight exposure for reliable solar charging.
Pros
- ✓
- Solar and USB dual charging for flexible power
- ✓
- Monitors up to ten tires at once
- ✓
- Color LCD with clear pressure and temp readouts
- ✓
- Easy auto-pairing out of the box
Cons
- ✕
- Solar charging is weak in low light conditions

GUTA10 sensors, 188 PSI
8.7OUT OF 10
Build Quality8.8
Ease of Use8.5
Signal Range9.0
Owner Verdict8.5
The GT20 is built for heavy trailers that run higher tire pressures and need more sensor coverage out of the box. It ships with ten sensors, and the display can handle up to 24 tires total. The pressure range goes all the way to 188 PSI, which covers the high-pressure tires found on large travel trailers, fifth wheels, and semi-trucks. That is significantly higher than the 144 PSI ceiling on most Tymate models.
The large color display shows all sensor data on one screen. You get six alert modes covering rapid pressure loss, high temperature, and slow leaks. Owners of triple-axle trailers appreciate not having to buy additional sensors right away. The long-range signal holds up well even with a 40-foot fifth wheel in tow.
Flaws but not dealbreakers. The GT20has a learning curve for its menu system. Some buyers report that scrolling through 24 tire slots takes a few extra button presses. The included sensors are also standard thread, so you still need to remove them to add air. If you prefer a simpler interface, the
Tymate TM7 earlier on this list offers a more straightforward display layout.
⚠Compatibility: The 188 PSI ceiling is overkill for standard passenger cars. This system is designed for heavy-duty applications with high-pressure trailer tires. Confirm your vehicle’s PSI range before buying.
Pros
- ✓Comes with ten sensors for multi-axle trailers
- ✓0-188 PSI range covers heavy-duty tires
- ✓Monitors up to 24 tires in total
- ✓Large color display shows all data clearly
Cons
- ✕Menu navigation takes getting used to
- ✕No flow-through sensor option for easy inflation
- ✕Display is bulkier than Tymate models

#4
TymateFlow-thru, solar charge
8.9OUT OF 10
Build Quality8.9
Ease of Use9.3
Signal Range8.5
Owner Verdict9.0
The TM12 solves the biggest hassle with external TPMS sensors: you can inflate your tires without removing anything. Its flow-through sensors have a built-in air passage, so you just press your air chuck onto the sensor tip and fill. No more unscrewing four sensors every time you top off at a rest stop. That alone makes it the most convenient pick for frequent tow vehicle users.
The display supports up to 12 tires and charges via both solar and USB. The 0-144 PSI range covers most RVs and trucks. The six alarm modes are the same reliable set found on the TM7. The 50-foot signal range works well for a tow vehicle and a single trailer, though owners of extra-long combinations report occasional dropouts.
Flaws but not dealbreakers. The flow-through sensors are slightly larger and heavier than standard external sensors. A few owners mention they protrude enough to risk scraping on very tight turns. The signal range is shorter than the GUTA GT20, so it may not work well with triple-axle trailers or long fifth wheels. For longer hauls, the
GUTA GT30 below includes a signal booster for up to 46 tires.
⚠Sizing: The flow-through sensors add about 1 inch of extra length to your valve stem. Check for clearance if your wheels have limited space near the valve.
Pros
- ✓Flow-through sensors allow inflation without removal
- ✓Solar and USB dual charging for cord-free use
- ✓Supports up to 12 tires on a single display
- ✓Reliable six-alarm mode system
Cons
- ✕Sensors are bulkier and may scrape in tight spaces
- ✕Signal range is limited to about 50 feet
- ✕No signal booster for extra-long combinations
Best for: RV and trailer owners who frequently check and adjust tire pressure and want to skip the hassle of removing sensors each time.
Masoll RV Tire Pressure Monitoring System: Best Budget Pick
#5
MasollSolar powered, 99 PSI
8.4OUT OF 10
Build Quality8.2
Ease of Use8.7
Signal Range8.0
Owner Verdict8.5
The Masoll is the most affordable way to get wireless tire pressure monitoring on your RV or tow vehicle. It comes with four external sensors and a solar-powered display, so you never need to plug it in. The 0-99 PSI range limits it to lighter RVs, SUVs, and cars. It supports the same six alarm modes as the more expensive Tymate models, covering rapid loss, high temp, and slow leaks.
Setup is straightforward. You screw on the sensors, place the solar display on your dashboard, and it pairs automatically. Owner reviews highlight the battery life as a strong point: the solar panel keeps it charged even on overcast days. The display is monochrome but readable, showing pressure and temperature for all four tires at once.
Flaws but not dealbreakers. The 99 PSI ceiling means you cannot use it on heavy-duty trailers that require higher pressures. It only supports four tires out of the box, so you would need to buy extra sensors for a dual-axle trailer. The signal range is shorter than the GUTA models. If you need to monitor more than four tires, the
Tymate TM2 supports ten tires for a modest price increase.
⚠Compatibility: The 0-99 PSI range is suitable for vehicles with recommended cold pressures under 80 PSI. Not designed for high-pressure trailer tires.
Pros
- ✓Lowest price point in this lineup
- ✓Solar charging with long battery life
- ✓Simple auto-pairing sensor setup
- ✓Six alarm modes for comprehensive coverage
Cons
- ✕0-99 PSI range limits it to lighter vehicles
- ✕Only supports four tires out of the box
- ✕Shorter signal range than GUTA models
Best for: Budget-conscious RV and SUV owners with lighter tire pressure needs who want reliable monitoring without a high upfront cost.

#6
GUTASignal booster, 46 tires
8.6OUT OF 10
Build Quality8.7
Ease of Use8.0
Signal Range9.5
Owner Verdict8.4
The GT30 is the heavy lifter of this lineup, designed for commercial operators and RVers with multiple trailers. It monitors up to 46 tires across three separate trailers and includes a signal booster for reliable coverage on the longest rigs. The 0-188 PSI range matches the GT20 for heavy-duty applications. The included ten sensors give you a solid start, and you can add more as needed.
The signal booster is the standout feature. It plugs into the trailer’s 12V system and extends the range so the display in your tow vehicle never loses connection. Owners of 50-foot fifth wheels and triple-axle horse trailers report rock-solid signal with the booster installed. The display shows all tire data clearly, and the six alert modes work the same as on the GT20.
Flaws but not dealbreakers. The GT30 is the most expensive system here, and the setup is more involved because you need to install the signal booster. Some buyers find the display interface dated compared to the Tymate units. It also uses standard external sensors, so you have to remove them to add air. If you do not need multi-trailer support, the
GUTA GT20 covers up to 24 tires without the booster complexity.
⚠Warranty: GUTA offers a standard 12-month warranty. Check the product listing for the specific warranty terms and return policy before purchasing.
Pros
- ✓Includes a signal booster for long rigs
- ✓Monitors up to 46 tires across three trailers
- ✓0-188 PSI range for heavy-duty applications
- ✓Comes with ten sensors in the box
Cons
- ✕More expensive than single-trailer alternatives
- ✕Signal booster adds installation complexity

Build Quality8.8
Ease of Use9.0
Signal Range8.6
Owner Verdict8.8
The TM3 is the best balanced option in the Tymate lineup, combining solar charging with a color display and support for up to ten tires. It uses the same 0-144 PSI range and six alarm modes as the TM7 but adds the convenience of solar and USB charging. The color LCD is bright and easy to read, even in direct sunlight. For most RV owners, this is the sweet spot between features and price.
Setup is identical to the other Tymate models: screw on the four included sensors, place the display on your dashboard, and it pairs automatically. Owner reviews consistently mention the long battery life when using solar charging. The display shows pressure and temperature for each tire, and you can toggle between PSI, BAR, or kPa units. It is designed for a tow vehicle and a single trailer, which covers the majority of RV setups.
Flaws but not dealbreakers. The TM3 does not include flow-through sensors, so you have to remove them to inflate. The 50-foot range is adequate for most combinations but falls short for very long fifth wheels. Some users wish the display mount was adjustable for better viewing angles. If flow-through sensors matter, the
Tymate TM12 offers that feature for a similar price.
⚠Sizing: The TM3 display measures roughly 3 inches square. Check that your dashboard has a flat, unobstructed area for the solar panel to work effectively.
Pros
- ✓Solar and USB charging for flexible power
- ✓Color LCD readable in bright sunlight
- ✓Supports up to ten tires on one display
- ✓Reliable six-alarm coverage for pressure and temp
Cons
- ✕Standard external sensors block inflation access
- ✕Signal range is limited to about 50 feet
- ✕Display mount is not adjustable
Best for: RV owners who want solar convenience with a color display and the capacity to monitor a tow vehicle plus a single trailer.
Buying Guide: PSI Range, Sensor Type, Power Source, and Signal Reach
Choosing the right Tire Pressure Monitoring System (TPMS) comes down to four main factors. Here is what you need to consider before hitting "buy."
How much PSI range do you need?
The pressure range determines which vehicles the system works with. The Tymate models (TM7, TM2, TM12, TM3) and the Masoll max out at 0-144 PSI, which covers passenger cars, SUVs, light trucks, and most RVs. The GUTA GT20 and GT30 go up to 0-188 PSI, which is necessary for heavy-duty trailer tires, fifth wheels, and semi-trucks that often run at 110+ PSI.
If you drive a standard RV, 144 PSI is plenty. If you haul a loaded gooseneck trailer, go with the GUTA. Knowing your recommended cold tire pressure is the first step in narrowing your options.
You can find it on a sticker inside your driver's door jamb.
External sensors vs. flow-through sensors
Every system here uses external sensors that screw onto your valve stems. They are easy to install and replace. The trade-off is that most require you to unscrew the sensor to add air.
The exception is the Tymate TM12, which uses flow-through sensors that let you inflate directly through the sensor body. That convenience matters if you check and top off pressures frequently. For most owners, standard external sensors work fine, but if you are the type who checks air weekly, the TM12 saves you a lot of time.
You can always pick up a stick tire gauge for quick manual checks, but the flow-through design eliminates the hassle entirely.
Solar, USB, or 12V power
The power source affects where you place the display and how often you need to charge it. The Tymate TM7 runs on 12V DC, so it needs to be plugged into a cigarette lighter or USB port. The Masoll runs purely on solar.
The Tymate TM2, TM12, and TM3 offer both solar and USB charging, giving you flexibility. Solar works well if your dashboard gets direct sunlight for most of the day. If you park in a garage or drive in cloudy conditions, solar-only models may struggle to stay charged.
Systems with USB backup let you top off manually when needed. The GUTA models use a standard 12V plug, which is reliable but adds a cord to your dashboard.
Signal range and booster needs
Signal range matters when you are towing a long trailer. Most Tymate models and the Masoll have a range of roughly 50 feet, which is adequate for a tow vehicle and a single trailer up to about 40 feet. The GUTA GT20 has a similar range but supports more sensors.
The GUTA GT30 goes further by including a signal booster that plugs into the trailer's 12V system, extending the range considerably for triple-axle and long combination rigs. If you frequently tow a 50-foot fifth wheel or have multiple trailers, the GT30 is the only reliable choice. For standard setups, 50 feet is enough.
To see how these factors play out on real picks, compare the Tymate TM7 RV Tire Pressure Monitoring, Tymate TM2 RV Tire Pressure Monitoring and the GUTA GT20 Trailer Tire Pressure Monitoring reviewed above.
Who Should NOT Buy a Tire Pressure Monitoring System
A TPMS is the wrong purchase for two kinds of buyers. Here is who they are and what you should look at instead.
You only drive a single passenger car short distances
If you commute in a sedan or compact SUV and rarely go on long road trips, a TPMS adds complexity you do not need. Most modern cars already have a factory-installed Tire Pressure Monitoring System that alerts you when pressure drops. Spending extra money on an aftermarket system gives you little benefit.
You are better off keeping a stick tire gauge in your glove box for monthly manual checks. It costs a fraction of the price and tells you the same information.
You need to monitor tire temperature data for racing or heavy towing
Consumer-grade TPMS like the ones here show tire temperature as a supplementary reading, but they lack the high-precision sensors and data logging that serious users need. If you are track racing, off-roading at high speeds, or hauling critical loads where tire temperature is a safety factor, you need a commercial-grade system with pyrometer-level temperature accuracy and real-time data export. These consumer models send alerts for high temperature, but they do not provide the granular data needed for performance analysis.
Look at dedicated racing telemetry systems or industrial TPMS designed for fleet trucks.
Final Verdict
The Tymate TM7 RV Tire Pressure Monitoring is the best tire pressure monitoring system for most RV owners because it combines a bright color LCD, six comprehensive alarm modes, and straightforward installation for up to five tires. It is simple, reliable, and does exactly what you need without overcomplicating things.
Want solar charging and the ability to monitor up to ten tires? The Tymate TM2 gives you that flexibility with USB backup. Need to inflate without removing sensors?
Get the Tymate TM12 with flow-through sensors. Hauling a heavy-duty trailer with high-pressure tires? The GUTA GT20 offers 188 PSI coverage and comes with ten sensors.
Managing multiple trailers or an extra-long fifth wheel? The GUTA GT30 with its signal booster is your only real option.
Before you buy, check the Who Should NOT Buy section above. If you are still unsure, remember that any TPMS is better than none when it comes to catching a slow leak before it becomes a blowout.
FAQ
What is the best tire pressure monitoring system overall?
The Tymate TM7 is the best choice for most RV and tow vehicle owners. It has a large color display, six alarm modes for pressure and temperature, and supports up to five tires. Its 0-144 PSI range covers standard RVs, trucks, and SUVs.
Do I need a TPMS for my trailer or RV?
Yes, especially if you tow a trailer. A Tire Pressure Monitoring System alerts you to slow leaks and rapid pressure loss before a tire fails. Blowouts on trailers are dangerous and can cause loss of control.
TPMS gives you real-time data so you can pull over and fix the issue early.
Can I install a TPMS myself?
Yes, all the systems here are designed for DIY installation. You screw the external sensors onto your valve stems, mount the display on your dashboard or windshield, and plug in the power. The sensors pair automatically with the display within a minute.
No special tools or mechanical skills are needed. For proper installation techniques, check out our guide on how to use a tire pressure monitoringsystem.
How many sensors do I need for my setup?
You need one sensor per tire. The Tymate TM7 and Masoll include four sensors, which covers a tow vehicle. If you have a trailer with two axles, you need at least eight sensors.
The Tymate TM2 and TM3 include four but support up to ten, so you buy additional sensors separately. The GUTA GT20 and GT30 include ten sensors, which is enough for a tow vehicle and a tandem-axle trailer.
What is the difference between the Tymate TM2 and TM3?
Both support up to ten tires and use solar and USB charging. The TM2 has a slightly larger display and a higher owner satisfaction rating. The TM3 adds a color LCD and is a newer model.
In practice, the TM2 is the more proven option with a 4.3-star average, while the TM3 offers a slightly improved screen design.
Can I use a TPMS on my car if it already has factory TPMS?
Yes. Aftermarket systems like these work independently of your factory system. They add value if your factory system only gives you a warning light without showing the actual pressure reading.
These displays show the exact PSI and temperature for each tire, which gives you more information than the dashboard warning alone.
How long do the sensor batteries last?
Manufacturer specifications indicate the external sensor batteries last 3-5 years depending on usage and temperature cycles. When a sensor battery dies, you replace the entire sensor unit. Replacement sensors are available from the manufacturer.
Keep a spare set if you do a lot of long-distance towing.
