When you change wheel and tire sizes, you change the rolling circumference. The vehicle control modules use a preprogrammed measurement to determine shift points, torque control, and anti lock braking function. When this number is changed on the vehicle and not the computers, you have problems. Aftermarket programmers might help with this problem, but are not GM approved. The aftermarket companies did not design the corvette, GM did. If you run into problems, the wheel and tire companies probably won't be much help and GM won't help if the vehicle has been modified.
