Tire size does not affect it. The tire will still spin 1 time for every 4.56 rotations of the driveshaft. However, because the tire has a bigger circumference it covers more ground in one rotation which is the reason it throws the speedo off.

You are right tire size does not affect the revolutions of the tire it just changes the distance traveled in the rotation.

Width won't make a difference in your RPMs but if you don't like the look I can understand. You may want to look into getting your ECM calibrated for the gears because I think that might be throwing off your shifts a lot theres no reason for you not to be able to reach over 70 with 33s and 4.10s

Oh i can hit 70. Its just the truck sounds like its running so hard it kinda pains me to do it. Feel like im about to throw a rod or something. I will prob go with those 255/85 since they are supposed to be "perfect" for a 7 in wide rim

Well guys sorry for the missleading info....I'm gonna just go ahead and throw 90% of what that instructor taught me out of the window! Thanks for teaching me something new and clearing it up.
