That's because of your 4.88s Haddix. That's what i was asking about earlier... Tire size isn't the only variable. If you regeared, then the normal tire size calculation isn't right. The new gears sorta split the difference. That's gotta be why LINY's #s are so off from ours. I would just like to see a calculator that takes the gear ratio change into consideration too. When my speedo reads 70, the GPS said 75. You have a slightly bigger spread in your numbers than I do Haddix, but you're running 35s and 4.88s against my 33s and 4.88s, so that's why (at least I think so).
