Is it possible to reprogram the speedometer to read accurately with oversized tires? With my 275/60/R20s it's off by about 4 MPH at 70 MPH. 70 MPH on the speedometer is really 74 MPH.

Assuming these trucks take programing like any other Ford car yes you would need a handheld tuner and you would then have the option to change your tire size in the program. I deal with Mos Speed Shop on the Marauders and Mustangs we do. They should be able to help you out as well.

I should have got them to do it when the roadforce balanced the new tires and wheels for me.
Or any good shop that does off road jobs and they should be able to reprogram the truck
