While on the road, it is very important to regularly maintain your tires and make sure they're inflated correctly. If your tires are underinflated or overinflated, they'll develop irregular tread wear and become prone to overheating and blowing out. The TireMinder A1AS TPMS helps protect your investment and keep your family safe by monitoring your tires and alerting you of any signs of danger before disaster strikes.

10 Waterproof Sensors with Bluetooth

This TPMS includes 10 sensors that let you individually monitor each tire on your application for changes in pressure and temperature. These brass sensors are able to work on rubber, steel, chrome, or nickel valve stems. Every 6 seconds, they will check the pressure and temperature again, and use Bluetooth to send that information directly to the monitor or smartphone app. These durable sensors are waterproof, which means that they can be used on boat trailers and other marine applications.

Simple Setup with Monitor and App

Unlike most other systems, this TPMS lets you choose between using the monitor or an app on your smart device as the screen. The TireMinder TPMS 2.0 app is free to download and use. For Apple smartphones and devices, it's compatible with models iPhone 7 and iPad 7 and newer. For Android smartphones, it's compatible with model Android 4.4 and newer. However, if you decided to use the app, you will still have to have the monitor in operation within 10 feet, as it is crucial for helping to bridge the Bluetooth transmission between the sensors and your phone.

TireMinder 6-Sensor TPMS Setup

The monitor or smartphone app will provide you with visual and audible cues to warn you of dangerous changes in tire pressure and tire temperature, as well as alert you of changes with the monitor battery, sensor battery, and sensor signal. Before you begin setup, make sure the monitor has been charged and the repeater and sensor batteries have been installed. If you have decided to use your smart device as the monitor, download the app and connect to Bluetooth.

TireMinder 6-Sensor TPMS Setup

Select your RV or trailer configuration or the locations of the tires you want to monitor. Then select one tire location, install a sensor on the corresponding tire on your RV or trailer, and the current PSI will automatically appear on the screen. With the purchase of additional sensors (sold separately), you can monitor up to 22 tires, which is perfect for a fleet. Sensors can be added, moved, deleted, or replaced at any point, even after initial installation.

TireMinder A1AS TPMS Setup

You can set the tire pressure in psi, Bar, and KPa. If you choose psi, you can set the tire pressure anywhere from 0 psi to 199 psi. As for the temperature, you're able to switch between degrees F and degrees C, and the system will alert you if the temperature exceeds 167 degrees F. With both the monitor and the app, you are also able to disconnect and reconnect to different vehicles, RVs, or trailers. This is useful for those who switch between different applications, such as a Class A motorhome owner who sometimes tows a car.

RHINO Repeater Boosts Signal

TireMinder TPMS RHINO Repeater

This repeater helps improve 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 monitor is strong and continuous. 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.

Easy Installation

TireMinder A1AS TPMS Installation

This TPMS system includes 20 batteries, 10 locking nuts, 10 O-rings, a wrench, and an adhesive. Once the batteries have been inserted and covers have been re-installed, remove the cap of your valve stems, thread the locking nuts onto the valve stems, and install the sensors. Lastly, secure the locknuts against the sensors with the wrench.

The weatherproof and dustproof Bluetooth repeater can be installed anywhere on the exterior of your RV or trailer between the rear axle and king pin. The optimal mounting location for a towable camper is toward the front whereas the optimal mounting location for a drivable RV is toward the rear. it is not recommended to install the repeater inside your vehicle, as you might experience signal blockage. Use either the adhesive (included) or hardware (not included) to attach the repeater and wire it to a power supply line. In order to reduce vibration, make sure it's securely mounted. Then connect the black wire to ground, and the red wire to power. Zip-ties are included to fasten the booster and wires to your RV or trailer.

Quick shipping and great service as always from etrailer. The Tire Minder system was super easy to install and set up for my class A RV and Jeep tow vehicle.

- TM79FR

At this point I have only begun to install the TPMS, but like the two previous orders it arrived quickly, and was well packed. The two previous purchases, Air Force One and Blue Ox tow bar are now both installed and I'm impressed with the concise instructions and the quality of the materials.

met all our expectations. We are very happy with its performance.

This is the best TPMS I have ever used! I have been RVing for 40 years and I have had several TPMS systems. The TireMinder is super easy to set up and very easy to see and use. I wish I had this for years!

- TM79FR

Back ordered but understood. When etrailer received it they shipped it fast an I got it. Well worth it

Excellent purchase RV and trailer tires

- TM79FR

This product was excellent. It worked exactly as it should. I highly recommend this product.

- TM79FR

Easy set up. The only thing I stress about now is the other drivers

- TM79FR

Best price is from etrailer, as with other products I've purchased over the years. The Tireminder is to replace a 10+ year old model, which intermittently would lose connection to my tow vehicle. The new model has a booster and instructions show it to be a bit more user friendly. I've prepared for, but haven't installed the unit yet. I like the new, larger monitor. Instructions indicate the RV and the tow vehicle can be separated (removed) from monitoring when running errands in your towed vehicle.

It is very popular for towing setups since it will display each tire from both the trailer and vehicle on one monitor right in front of you. It comes with everything you need and tons of extras. It will come with two more sensors than you need but you can simply save these for spares. The system has alerts you can set...

The kit only comes with 10 sensors but you can add up to 12 more using the Brass Tire Sensors for TireMinder TPMS part # TM-2Brass which are sold in pairs only.

    The TireMinder A1AS TPMS for RVs and Trailers part # TM79FR is what I recommend for a flat-tow setup. It comes with sensors for the towed vehicle and towing vehicle.

  • Where Should Signal Repeater/Booster of Tire Minder TPMS System Be Installed
    By 'transmitter', I believe you're speaking of the repeater/booster included with the # TM79FR Tire Minder TPMS that boosts the signal from the sensors to the monitor. The folks at Tire minder tell me that the installing the booster inside the vehicle could significantly reduce its range, so they recommend installing the booster under the RV using the provided zip ties as outlined in the installation instructions. The booster needs to be connected to a 12v power source and a ground,...

  • Do I Need Brass or Aluminum Transmitters with my TireMinder TPSM System
    This is a good question, and it's going to vary between RVs and towed vehicles, so I'll try to break this down. The short version of this is that for your setup you'll want to use brass transmitters. Towed vehicles will have either rubber (brass) or metal (aluminum) valve stems in the wheels. If you have a rubber valve stem, you will need brass transmitters like the ones that come in the TireMinder # TM79FR. If you have a metal valve stem on your towed vehicle, you will need aluminum transmitters...

    If you are worried about pressure increase due to heat build-up then the best way to get ahead of the issue is with a TPMS that will warn you when temperature and or pressure build up is to a point that could lead to the potential for a blowout.

  • Can I Use TireMinders with Valve Stem Extensions
    As long as you use valve extenders that are not airless (don't hold air) and are constructed of brass or steel, like the Wheel Masters # WM8005 which do hold air, so they will be compatible with a TireMinder system. TireMinder has a few different options with the A1A-S systems depending on how many sensors you need. If you need as many as 10 sensors, you can use the # TM79FR. There is also a 4 sensor system # TM49FR and a 6 sensor system # TM69FR. These systems can also be paired to your...

  • Can TireMinder i10 be Used with Multiple Single Axle Trailers
    You could use the TireMinder i10 part # TM56FR for your three trailer setup and it would work great. The sensor spots on the display that aren't being used would just show blank and the other sensors would still show up like you'd want to. Non-flow through sensors like this would work just fine for your setup since you don't plan to be adjusting air pressure frequently. Essentially these would be basically like valve stem caps. Removal is not difficult. To do a smart phone setup...

You can then add the remaining 6 sensors for the aluminum valve stems on your Class A with the Aluminum Tire Sensors for TireMinder TPMS - Qty 2 # TM-2ALUM, which you'll need 3 sets of for the 6 wheels; these are the correct...
