just figured i'd share with you guys, if anyone has to ever have their computer changed to accomodate larger tires, the number that worked for my 35's was 600 revs/mile. a 34.8 was suppose to be 598, i figured mine were wore down a little bit, so i went with 600, and its dead nuts. its nice to have an accurate speedo and odometer now. once again, i had to show the "tech" how to do it with the DRB tool.
