So in 7 actual traveled miles according to mile markers, my ODO only showed 6 on the button. So according to my calculations that puts my ODO off by .1428571 per mile shown.
Adam it's not that I doubt your calculations, but your truck came with 34.1" tall tires and you now have 35" tall tires. The actual difference is likely to be more in the 3-4% range not 14%. The math just doesn't add up.
