    Tyson Boyer form Dill Air Controls explains how to install an aftermarket tire pressure monitoring system on your vehicle or trailer.

    Tyson Boyer: Hi! I am Tyson Boyer with Dill Air Controls. Today I'm going to discuss how to install an aftermarket tire pressure monitoring system that is suitable for most types of trailers, RVs or vehicles not already equipped with TPMS. Tire pressure monitoring systems have proven their worth in decreasing accidents, down time on the roadside and cost associated with repairs.

    TPMS allows a peace of mind by alerting the driver of unsafe conditions due to low tire pressures. Some TPMS kits such as the Dill systems allow anyone with a non-equipped TPMS vehicle or trailer the ability to install sensors in the tire and wheel assemblies which will monitor the temperature and air pressure simultaneously. The receiver mounted on the dash shows tire pressure and tire temperature for each wheel position as it cycles between them each sensor is mounted inside the tire and attached to the valve stem. The sensor transmits a signal to the receiver on the dash with pressure and temperature information.

    Select a Unit that provides coverage for the number of wheels you are installing sensors into. Systems are available from 2 wheels up to 10 wheel positions. The display comes standard with 10 positions available in the event you want to upgrade in the future. The following valve stems are commonly used in aftermarket kits such as the Dill TPMS.

    Brass and aluminum along with the different angles allow the end user options to best fit their application. This system can be used in applications requiring up to a 144 psi at cold inflation pressure. Using the appropriate valve stem for the wheel, install the sensors into the wheels and torque the valve hex nut to the recommended specification. Be sure to place the ID chip that corresponds with the sensor in the proper wheel position as shown.

    The wheel positions are identified on the back of the dashboard display unit and must correspond to the final wheel installation location. Small vehicles and trailers may pick up the sensor transmissions when the vehicle is in motion without the use of an antenna extension. To help access sensors that may be further from the receiver, attach the antenna cord to the back of the display and run the antenna to a location where I can pick up the sensor signals with minimal interference.

    It is recommended to attach the magnetic bottom to the underside frame at the back of the towing vehicle for maximum reception. Mount the display unit where you can see it and hear it without obstructing the driver's view. Connect it to your power source using the hardwiring harness or the auxiliary adapter. The display will now search for and recognize the sensor's air pressure and temperature by location because the sensors are shipped in sleep mode, driving the vehicle above 20 mph for several minutes may be required to activate them. All units are shipped from the factory with a cold inflation pressure setting of 35 psi.

    If a tire pressure decreases by 20% or increases by 30% of the baseline setting, the display will flash and an audible alarm will sound. The display will also alert the driver for tire exceeds 176 Fahrenheit or 80 Celsius until the problem is corrected. To adjust the number of wheels being used, the baseline air pressure or for further information and troubleshooting, refer to the manual provided.

    Now you can drive knowing that you are protecting your investment and precious cargo with an aftermarket TPMS kit.
