Tire Rev's per mile question

I just got some Dick Cepek FCII's in a 33x12.50x17. I need to know what to set the revs per mile on my tuner at.

I cant find a calculator to convert english tire size. Anyone know?

dave it's even easier to do this with all the measurements in inches instead of a metric tire.

5280/(d*pi/12) = about 611 revolutions per mile
