changing your tire size effectively changes the overall gear ratio of a vehicles axle.
Well, perhaps it's just a wording thing... your gear ratio does not change, but does impact engine RPM at speed that's for sure...


I calculate a 19.44% reduction in Engine RPM.
Thought it was interesting got that out of the back of a Reider Gear catalog.Yours makes more sense.
NoNoNo not my tires that was theres in the artical.
