Default 2012 Silverado speedometer error
Changed from stock Goodyear Eagle LS2 (275/55/20) to Cooper Discoverer AT3 (275/60/20). Of course I now have error with the speedometer. How to correct this?

the factory scan tool will allow you to go into the ebcm and select the tire type and size. this will correct your problem.
They do sell an aftermarket programmer that will do the same thing.
