SCT and Tire Size
Alright, I have had the 35's on my truck for a few weeeks now, and finally got around today to pulling my XCal2 out, and changing the Tire Revs/Mile to make my speedometer accurate.
I tried 575, which is the number I calculated...no chage to my speedometer(I am using my GPS to find my true speed). I tried Rev/Mile numbers from 545 to 580, with no change.
Anybody know what's up? I thought that setting affected the speedometer.
