If anyone else thinks this should be stickied, Chime in, because I definitely think it would be handy, and it would cut down on a lot of the " what backspacing do i need" kind of questions on the board. GREAT Tire size calculator that does backspacing and everything.

I also use this one for tire sizes & gear ratios to figure out MPH
