Keeping your tires inflated to the appropriate pressure is critical for the safe operation of the vehicle. Keeping the right amount of air in the tire will provide the maximum life for the tread of the tire. For many years vehicle manufacturers have put tire pressure sensors into the vehicles that they have made. There are aftermarket suppliers that also produce a tire pressure monitoring sensor that can be installed on a vehicle. This will allow the driver to monitor their tire pressure without having to use a tire pressure gauge to do it manually.


There are several options when it comes to TPMS.  It is beneficial to understand the advantages offered by the different tire pressure sensors. 

OEM Sensors


OEMs are a tire air pressure sensor that is installed at the factory when the vehicle is assembled. They are placed either inside of the tire or near the valve stem of the tire. The sensor will send a signal to the car module that will report the tire pressure to the instrument panel. If the sensor that is purchased does not communicate on the same frequency as the OEM, a fault will display on the panel. There are some manufacturers that will change the frequency and design of their tire monitoring system between model years so it is important to make sure that the OEM sensor that is bought will be compatible with the make and model of the vehicle that you own.

Aftermarket Tire Pressure Sensors


There are both pre-programmed and programmable sensors available for OEM systems. When you are purchasing this type of sensor you will want to make sure that you check for compatibility. These tire sensors are not always installed in the same way as the OEM sensor so you will want to read the installation instructions for mounting issues on the tires. Mounting to some of the types of tires may require modifications so make sure that you are familiar with the types of mounting options that are available.

Add on Tire Sensor Systems


For a vehicle that is manufactured without a stock tire pressure sensor there are complete tire monitoring systems available. These add on systems come with 4 wheel mounted sensors as well as a display unit that will be located near the passenger compartment of the car. There are some systems that have a dash mount that will hold the monitor in place and display the tire pressure reading.


There is one type of tire monitoring system that will use a sensor those screws onto the valve of the tire. This eliminates the need to mount a sensor inside of the tire.


Add on systems are perfect for people who want to monitor their tires, but have a vehicle without a built in OEM system. These tire pressure monitoring systems can easily be added to any type of vehicle and make it easy to check your tire pressure at any time.
