Tire Size - Speedometer vs Actual MPH Calculator. MPH difference actually changes as you wear the tire tread down. Rhinebeck01 and andrech0586 like this. Your Dealership can re-calibrate your JL's speedometer for you. Will cost approx. $125.00+- for the dealership to do. Of course, the day will come when there will be an aftermarket tool/module to do the re-calibration. Rhinebeck01 likes this.
FN wheels (BFDS or Six Shooters) and WHAT tire? Will be getting a Silver Sr5 premium T4R in Jan 2015... First thing will be to change wheels and tires....looking at the FN wheels and can't decide between a 18 inch wheel (BFDs) or a more stock sized 17 inch wheels (Six Shooters).
