Frequently Asked Questions

Can aftermarket wheels affect TPMS sensors?

Yes. Some aftermarket wheels, especially those with thick construction or certain alloys, can partially block the TPMS radio signal, causing intermittent communication failures.

What happens if I drive with a failed TPMS sensor?

You can drive safely, but you will not have tire pressure monitoring for that wheel. Check the tire pressure manually and regularly until the sensor is replaced.

Is it worth replacing all TPMS sensors at once?

If one sensor has failed due to battery death, the others are likely near end of life as well. Replacing all four during a tire change saves on repeated tire dismounting labor costs.
