Are they physically in the tires..? can they be transfered to a new set of wheels..? If not, were are they located..?

 

Its actually the wheel speed sensors that are used for ABS that are also used for tire pressure monitoring. When a tire is low, that wheel will rotate at a different rate than the other wheels. After it gets past a certain point it will trigger the light. You should not have any problems after isntalling new wheels/tires. Just be sure to reset it to the new parts after you install them. The instructions on setting the system are in your owners manual.

 

Great to know!... I had wondered about that... (if I was going to lose this as an option when changing my rims) Thanks guys!

 

yes to confirm.. i've seen my wheels without the tires, and no sensors on the wheels.. it is all via the abs sensors..
