Buy a Predator or Quadzilla and recalibrate.

I put 325/60R18 and According to my GPS it was 4-6 mph off. One reason Im going with the Quad Stealth

I just used the Quad Stealth to recalibrate for the 315/17's and it was oh so easy! Oh yea, I added a few horses too while I was at it!

Quadzilla folks were great to deal with and the instructions were real good too!
