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.

4 Waterproof Sensors with Bluetooth

This TPMS includes 4 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 8 batteries, 4 locking nuts, 4 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.

Expensive option for a 30 ft trailer. Sensor failed (internal connections fell apart) - $80 to fix. Poor connections for booster. Cheap tiny alligator clips. For the cost this is not a good product.

I will have the manufacturer reach out to you.

Great attention to customer service! Did what they said they were going to do! Hard to find these days. I will be back!

  • Best TireMinder Tire Pressure Sensor Setup for 30 ft Airstream
    The best option for a Tireminder is the part # TM49FR that you referenced which has a signal booster that will work great on your 30 foot setup. The key to getting the range is the placement of the signal booster. If you can make sure it has a clear of a path to the receiver you'll have best results.

  • How Accurate Are Valve Stem Temperature And Pressure Sensors
    A tire temperature and pressure monitoring system, such as the TireMinder A1AS TPMS for RVs and Trailers w/ Signal Booster - Bluetooth - 4 Tire Sensors # TM49FR, gives very accurate readings to tell you if the tire has a puncture and is losing air or if the temperature is above the normal operating range due to an overheating brake caliper or wheel bearing. This system runs a test every 6 seconds to check the temperature and pressure of the tire. The sensors are threaded into the valve...

  • How To Determine a Trailer Tire's PSI Rating
    In order to find the correct trailer tire inflation value, you must look on the sidewall of the tire itself. This will display the correct cold fill psi. The weight of the trailer is not a factor when determining psi but it is when selecting the correct load range. If you're looking to get more real-time info on both psi and temp which can be used to better predict failures then I highly recommend a TPMS like the TireMinder A1AS TPMS for RVs and Trailers part # TM49FR. I have attached a...

  • Recommended TMPS for Trailers Compatible with GM
    I do have an option for you but we don't carry any GM compatible TPMS for trailers. The only option we could provide is a new kit specific for trailers, the TireMinder A1AS TPMS for RVs and Trailers part # TM49FR. The TireMinder A1AS can be used with either a mobile device or the included monitor. It threads onto the end of a standard vale stem so there is no need to replace the actual valve stem itself. I have attached a review video below.

  • Best TPMS for Trailers
    The TireMinder A1AS TPMS part # TM49FR is my favorite TPMS. It's available with 4, 6 or 10 sensors. If you only had a single axle trailer for example then you would just go with the four pack and keep the extras as spares. That said, if you wanted the vehicle's and trailer's tire pressures and temperatures on one screen you could go with an option for more sensors like the six pack part # TM69FR. The sensors are also available separately. It comes with its own monitor or you can use your...

  • Can the TireMinder A1AS Be Configured to Pull Two Trailers
    You can definitely add more sensors if needed. The TireMinder A1AS TPMS for RVs and Trailers w/ Signal Booster - Bluetooth - 10 Tire Sensors # TM79FR will include 10 sensors, but the monitor can handle up to 22. The TireMinder Brass Tire Sensors # TM-2Brass come as a pack of 2, so you will need to order 2 sets to get you the amount needed. Unfortunately, the Booster is not available separately at the moment, so the best thing to do would be order the TireMinder A1AS TPMS for RVs and Trailers...

  • What Devices Will the iN-Command TPMS for RVs, Trailers, and Vehicles Work With
    The iN-Command TPMS for RVs, Trailers, and Vehicles part # NCTP100 is compatible with any smart device such as a mobile phone or tablet with access to either the Google Play or Apple App stores. If you prefer a dedicated monitor for the TPMS then you'll have to go with an option like the TireMinder A1AS TPMS for RVs and Trailers part # TM49FR.

  • What Causes One Tire On Tandem Axle Trailer To Wear More
    The most general causes of a tire wearing on one side faster than the others could be as simple as inflation not being consistent across both side, front to back and side to side or it could be a bit more involved such as a bent spindle. I recommend checking and replacing any worn or damaged suspension components first. For a replacement 205/75-15, I recommend the Provider ST205/75R15 Radial Trailer Tire part # TTWTRTM2057515C. A great way to keep up to date on real time pressure is with...

  • Aluminum Wheel and Tire Replacements for 25 Featherlite Horse Trailer
    I Recommend the Provider ST235/80R16 Radial Tire w 16" Viking Aluminum Wheel # A16RTK8BMMFLHD. It comes with a radial 10-ply load range E tire. This wheel and tire package includes a 2-Year Platinum Plus warranty including emergency tire change service and other benefits. The included center cap can be removed for easy access to hub bearings for EZ lube. We do not have any 7.5x16 wheel and tire packages at this time so I went with the 235/80R16 as this is what I could find as recommended...
