Re: Site for tire sizes and spedometers
This site gives same numbers as my trusty calculator, but keep in mind you're probably about 2-3% fast from factory, so some of the slightly larger than stock tire/wheel combo's are probably bringing you back into dead accurate speedo range....which is one reason I chose my slightly larger than stock diameter tires. Cody went one size larger than I did, and I bet he's either dead on or only slightly reading slow, no big deal, but enough to be careful if he runs thru his buddies radar gun.
