315/75/16 speedo change on a 94 4x4 with 3.5 rear gears
Who in here is running 315/75/16 tires with 3.5 rear gears? How do the tires effect the speedo at highway speed?

I have 315s, and I was off by about 8 mph at 65. You need a 28 tooth speedometer gear to correct your speedo. your odometer will be a little off, but according to my GPS, and my girlfriend's acura, speed is right on, and odometer is off.
