External Tyre Pressure Monitoring Sensor TPMS

TPMS External Tyre Pressure Monitoring System

Bluetooth TPMS External Tyre Pressure Monitoring System. Set custom alarms. Can monitor trailer and spare wheels as well. Indicates tyre temperature. The TPMS also gives alerts for leaks or tyre bursts. You can add as many tyres as needed. Perfect for when you have a trailer or caravan and multiple spares wheels.

Our TPMS sensors come in kits of 1, 2 and 4. As an example, if you have 4 wheels on the car plus 1 spare, and you have a trailer with 2 wheels and 1 spare, then you can use two kits of 4 to get the 8 total sensors you need. Or a common option is 6 TPMS sensors for car and trailer. Use the drop down menu to choose the kit of your choice.

If you do extensive driving on gravel roads, rocky trails, through mud, water, sand etc. the Internal TPMS units are recommended. External sensors should not be submerged in water or cleaned with high pressure jet. Please refer to manual for full instructions.
