How about some feedback on successfully changing the sensors to aftermarket rims. I have a 2007 Chevrolet extended cab. When the factory Generals wore out (20K) I went to new tires on Cadillac rims, stayed with 17's, and when the Michelins on them wore out, to 18" aftermarket rims and noisy Nitto's. The tire place I bought the Michelins would not change the sensors from rim to rims, so now and then I do without. I have a new set of tires and want to put the sensors in the 18" aftermarket's. Anyone have any success with this? Do the sensors have batteries that go bad in them?
