I guess I could have expounded on that. 689 rpm = 689 X 31 X pi
(3.14159) =
67101.22 inches. There are 63360 inches per mile. That means you
actually
travel 3741.22 inches more than is indicated by your vehicle. That's a
5.9%
difference.

My Trig is a little rusty. Why are you multiplying by pi? I assumed 689
rpm x 31" = 21359, but that doesn't equal a mile. So if that's the
correct equation if I input my 32" tire I should get an accurate
reading. 689 x 32" x pi = 69265.78, which would be 5905.78" more per
mile I'm racking up. Is that correct?
