I have the 33" BFG's They are appox. 1.5" bigger than stock so I calculated that I am actually travelling 4% faster and farther than indicated.
Can the dealership re-calibrate for the tires? Or do I have to buy a tuner?

dealer cannot do this. have to buy a tuner or the hypertech tire/speedo recalibrator
