Tire size / speedometer calibration
What engine?
If it's an EB, then the dealer might be able to re-program, but the available choices will likely not match the A/M tires. Really depends on the truck and the A/M tire size.
If it's a 5.0, then the SCT XCAL3 can re-program to any diameter. The dealer can also re-program; again limited by factory tires size offerings.
