They can't do it at the tire store, they will have to take it to Cadillac for that special tool to be waved over it. You will have to listen to the warning buzzer that thinks your tires are flat.
does anyone of you know how to reset the TPM valves when new tires comes on the rims????
Tomorrow I get my new Pirelli`s on the V rims and it`s at my local tire-store they never did a reset before!
Hope someone knows
