Why not just move the sensors to your new wheels. It's only a part of the valve and simply unbolts.
Hi i am told that they the sensors break easy, when taken off is this true?
Also the car is coming upto the time when the battery (in the sensor) will start being a problem, maybe a good time to remove and disengage the system rather than paying out £600 or so to have new sensor fitted.
Right guys i have finally worked out how to disarm the tyre sensor anyone needing advice please get in touch.
