This TireMinder Smart TPMS monitors the pressure and temperature level of the tires on your RV, motorhome, 5th wheel, motor coach, or trailer. The system utilizes sensors that attach to the valve stems of your tires. When a tire sensor detects an anomaly, it will wirelessly transmit an alert to the Bluetooth adapter, which relays the data to an app on your smartphone. Your smartphone will emit an audible alert to notify you of an issue and will display details regarding the anomaly. A signal booster is included to provide a constant, strong transmission, and to eliminate electronic interference.

Initial Setup

The TireMinder Smart TPMS is easy to set up and includes all of the tools and mounting hardware necessary for installation. First, attach the TireMinder sensors to the valve stems of your vehicle's tires. Next, install the Rhino signal booster in a protected area near the front or rear of your full towing setup, depending on your application. Set up the Bluetooth receiver in the cab of your tow vehicle near your smart device. Finally, install the TireMinder TPMS app from the Apple App Store or Google Play to your smart device and assign the sensor positions through the Learning Mode in the app. Once the tire sensors have been recognized by the app, you're ready to travel.

Note: Your smart device must be compatible with Bluetooth 4.0 to use the TireMinder Smart TPMS app. The app is compatible with iPhone and iPad devices running iOS 7+ and with Android devices running KitKat 4.4+.

TireMinder Smartphone App

App Diagram

  1. Temperature Reading - Displays the current temperature of your selected tire in Fahrenheit or Celsius.
  2. Pressure Reading - Displays the current pressure reading of your selected tire in psi, kPa, or BAR. Refreshes every 6 seconds. The Auto-Scroll option allows the app to scroll between all of your sensors automatically and display the pressure of each when selected. The number will display in red if there is a warning for the selected tire.
  3. Tire Sensor Icon - Indicates the installed tire sensor. The icon will be white if the sensor is not activated, or green if activated. The icon will turn red if the sensor detects an issue.
  4. Monitoring Mode - Shows up-to-date tire pressure information.
  5. Learning Mode - Displays during sensor installation. Lets you add and remove sensors to your system by simply touching the tire icon on the screen.
  6. Delete Mode - Lets you remove sensors from your system.
  7. Dialog Box - Displays detailed information about received alerts from tire sensors.

App Alerts

App Alerts

Specific text for app alerts will display in the dialog box. Once an issue is detected and an alert is triggered, the system will check the effected sensor every 6 seconds for updated information until the issue is addressed and the readings go back to normal settings.

App Functions

The app provides multiple options for displaying your pressure and temperature readings.

Auto-Update - Triggers instantly updated pressure readings.

Auto-Scroll - Scrolls between all of your sensors so you can view pressure and temperature automatically. Cycles at a rate of 6 seconds per tire.

Auto-Search - Lets you erase all of the previous pressure and temperature readings for a specific tire and refresh to find new, updated readings.

Bluetooth Receiver

Bluetooth Adapter

  1. Antenna - Receives data from the tire sensors. Keep the antenna up and extended to maximize electronic transmission distance.
  2. Power Button - Turns the receiver on and off. It is recommended that you always leave the receiver on to ensure a continuous connection between the tire sensors, receiver, and smart device. To turn the receiver off, press and hold the button for 3 seconds.
  3. Bluetooth Light - The blue light blinks when it's connected, and stays solid when it's disconnected.
  4. Alert Light - The red light blinks when tire issue occurs.
  5. Battery Light - The orange light blinks when the battery is low, and stays solid while the battery is charging. The light turns off when the battery is fully charged.

The TireMinder RV Bluetooth receiver acts as a relay between the tire sensors and the TireMinder TPMS app. It provides visual and audible alerts when a tire issue is detected, acting as a backup monitor to the app on your smart device.

A DC adapter with a Micro USB connection is included to charge the receiver's internal lithium-ion battery, and the receiver can be used while charging. It takes about 6 hours for the adapter to fully charge. A single battery charge will last between 2 and 4 weeks, depending on how much you use it. A notification will be sent to your smart phone if the battery is running low.

Tire Sensors

Tire Sensor Install Diagram

  1. Fasten the hex nut onto the valve stem by turning it clockwise. The nut must be positioned at least 1/4" from the top of the valve stem.
  2. Thread the sensor onto the valve stem and hand-tighten.
  3. Rotate the hex nut counter-clockwise towards the sensor. Use the included locking wrench to tighten the hex nut against the sensor.

Make sure your tires are inflated to the pressure level specified by the manufacturer prior to installing the sensors. These pressure levels will be used as baselines to determine the high/low pressure warnings. It's best to install the sensors when your tires are cool.

You can also install flow-through adapters (sold separately) that let you air up your tires without removing the sensors. Simply screw the adapters onto your valve stems, and screw the sensors onto the adapters.

Brass vs Aluminum Tire Sensors

TireMinder sensors

Your vehicle's tires will have either rubber or metal valve stems. RVs, motorhomes, 5th wheels, and trailers will generally have rubber stems with brass valve cores or metal stems with steel, chrome, or nickel valve cores - all of which work with the TireMinder brass sensors. This TireMinder kit comes with 4 brass sensors. You will only need aluminum sensors (TM-2ALUM - sold separately) if you're towing a car or light truck with built-in TPMS and aluminum valve stems.

It's important to choose the correct TPMS sensor for your vehicle. Pairing the wrong metals together may lead to galvanic corrosion, which makes it impossible to remove the sensors from the valve stem. If this happens, you will need to replace the valve stem or, in some cases, the whole tire. Matching the sensors to the construction of your valve stems will ensure the sensors won't corrode.

Rhino Signal Booster

Signal Booster

The TireMinder Rhino signal booster improves the signal strength and range of the sensors. It has dual Hi-Db antennas that let the booster cut through signal interference coming from wireless electronic devices used in surrounding automobiles. It also ensures that the link from the sensors to the Bluetooth adapter is strong and continuous. This is crucial for operating the TPMS on large vehicles such as RVs, 5th wheels, or motorhomes. The unit has a green light on the front panel to indicate it has power and a blue light that blinks when it transmits a signal.

Even though the booster is weatherproof, you'll want to install it in a protected area on the underside of your vehicle to prevent corrosion. For a towable RV or camper, the optimal mounting location for the booster is toward the front. For a larger, drivable motorhome or RV, the optimal mounting location is toward the rear. This allows the booster to communicate clearly with all of the tire sensors. Other possible mounting locations for the booster include your battery compartment, attached to your license plate light, or on the front of your car hauler.

Once you've mounted your booster in a good location, connect the red power wire and black ground wire to a 12-volt or 24-volt power supply line. The booster needs to be mounted securely to reduce vibration. Zip-ties are included to fasten the booster and wires to your vehicle or trailer.

TireMinder Smart TPMS for RVs - Signal Booster - 4 Tire Sensors - TPMS-APP-4

Average Customer Rating:  4.5 out of 5 stars   (24 Customer Reviews)

This TPMS monitors your RV's tire pressure and temperature and sends real-time info to an app on your smart device. Tire sensors run checks every 6 seconds and send alerts via Bluetooth. Early warning detections on app update every 4 minutes.


The hardware is well designed and well built. I like the repeater and the sensors are small and provide both pressure and temperature. Where the system as a whole failed was with the app software. If a trailer tire is losing pressure, I want to know about it so that I can address the issue quickly before there is a catastrophic failure. My expectation is for the app to raise an alarm that something serious is going on. However the TireMinder app only provides a single chime. The same notice one gets when receiving a text and then only if app is running in the foreground and the phone is not in do-not-disturb mode or asleep. In contrast the TireMinder app the Android clock app has a much more robust alarm for an event that it isn’t nearly as critical as a tire failure.


Timely product arrival, easy to install and works great on our 41 foot 5th Wheel. Knowing tire pressure is necessary for safe relaxing driving.


I had a flat tire on my last trip. After being camped (trailer unhooked) I had a flat tire on my trailer. I changed the tire and put the spare on. We were leaving that day so I stopped at a tire shop to get the flat fixed. The tire was perfect. The air leaked out of the TPMS monitor on the valve stem! Up to this point I thought the product was great. If anyone wants this Sysco to free come see me in Arizona before I throw it away. Do Not Buy This Product!!!


Used on 26' Flagstaff with an F-150 tow vehicle and does not require the signal booster module. Works great with either iPhone or Android phone and you Do Not need to keep checking your phone for and problems... because the TPMS receiver provides beeping alerts if the pressure or temperature of any tire exceeds or goes below set press/temp levels. Phone will displays temp and pressure for each tire and allows for custom settings. Would absolutely recommend.


After a year of use, and about 8,000 miles, our Tire Minder continues to work almost flawlessly on our 2-axle, 27-ft Airstream trailer. It certainly gives us confidence and peace of mind that all is going well. We have had a few occasional false alarms, but we've learned to wait a few minutes for a reset before panicking. We have yet to change the batteries in the sending units - still got the spares that came with the unit. Overall an excellent product, definitely recommend to others.


The pressure monitors were easy to install and setup. Using them on our first trip out since installing them. The peace of mind of being able to see the pressures and temperatures of the tire makes the trip less nerve-wracking. Despite the rough roads of New York and Pennsylvania the monitors have stayed securely on the valve stems.


Product worked as described. I’m still experimenting on where to place the booster but it seems to work anywhere I’ve placed it on the trailer. Setup was easy if you follow the instructions. By the way, if you have never ordered from etrailer you will be impressed with their service.


Works great

Great they even sent batteries and o rings for $5.00 shipping. Couldn’t buy batteries for that price. Great company.
Bob C - 09/14/2020


Pressure shows about 10 pounds under actual, but who cares. I want to know if I am losing pressure. Quite a few false alarms and it’s hard to reset. All in all I would buy it again.


This was easy to set up and gives such incredible peace of mind being able to see the trailer tire pressures and temperatures while towing. Works like a charm!


What great service. Shipping was very fast and the price was the best I could find on line.


Daniel M - 08/11/2021


Nice product. Luckily haven't had any tire issues yet.



Review from a similar TireMinder Smartphone in TPMS Sensor

Excellent product and customer service! Accurate and reliable. CR1632 batteries are hard to find so buy extras. Batteries last for several months. Occasionally I get a no signal from the farthest transmitters so I keep fresh batteries in them. Easy to program and use. Booster and trailer tires are 30’ apart. Booster is very easy to install with alligator clips and tie wraps.

Minimal false alarms. Batteries for the sensors are hard to find. I’m very happy with it.

Review from a similar TireMinder Smartphone in TPMS Sensor

The TireMinder TPMS is not a very good system. It has drop offs all the time and when a wheel drops off, I have to go thru the process of completely resetting that wheel. It constantly also gives either high or low temp reading on certain tires. I’m not one to complain but you asked for a review. I’ve got everything set up to their specs with the repeater under the coach on the outside. Would not recommend this to anyone. The only thing good about it is that allows me to know what my psi on the tires are before I get on the road.


Review from a similar TireMinder Smartphone in TPMS Sensor

This is my second Class C and my third TPMS but by far the best of the three. My first TPMS was hard wired to its own independent mini screen and this Tire Minder is bluetooth enabled and works flawlessly thru my iPhone. My second unit is what I considered a Tire Minder wannabe. It was Bluetooth enabled and also worked thru a smartphone but it only monitored sporadically at best. Needless to say, it didn’t make the cut and was returned. I’ve taken two trips this year using this system and I could not be happier with its solid performance. It was incredibly easy to install and set up by using the directions from the included booklet and App. I also like how it goes into sleep mode but still runs in the background. The first trip had me nervous because I didn’t think the unit was working but l finally realized it was working as designed. This is a great TPMS and I highly recommend this product especially because of the peace of mind it brings mile after mile monitoring my air pressure and tire temperatures.

    The TireMinder Smart TPMS like part # TPMS-APP-6 are waterproof but TireMinder does not recommend the transmitter box be submerged more than 30 minutes so as long as you are mindful of that you shouldn't have any issues launching your boat with the sensors installed. I recommend part # TPMS-APP-6 if you need 6 sensors or part # TPMS-APP-4 if you need 4. This particular system sends updates to your smart phone via an app so it is much more convenient then having a display screen in my opinion.

  • What Tire Pressure Do I need To Run In My Trailer Tires?
    The tire pressure you use in your tires should be what is suggested by the trailer manufacturer. This information is found on the trailer information tag that is generally found on the front drivers side of the trailer. The tag is similar to ones found on a vehicle in that it will give you the axle load rating and a manufacturer suggested tire pressure.

  • Recommendation to Replace 235/80-16 Tires on Trailer
    As you mentioned in your question, the highest load rating tire we have in the 235/80-16 tire size is a Load Rating E.

This radial tire has a maximum load of 3,520 pounds at 80 psi and an excellent maximum speed rating of 75 mph. The thing that sets this particular tire apart is the length and content of its warranty. This tire not only...

  • Max Tire Temperature on Kendra Loadstar 205-65-10 E Rated Tire
    The Loadstar K399 Bias Trailer Tire - 205/65-10 - Load Range E # AM1HP56 should be run at 90 psi when filled cold. Trailer tires are always to be run at their max psi listed on the tire when filled prior to getting on the road. Failure to do so may cause the tire to heat up more and wear unevenly eventually leading to failure. The actual operating temperature of a trailer tire will vary quite a bit based on weather, (inflation, as noted), driving speed and the actual weight load on...
