Hi all, Can someone please write me the formula for working out road speed if i have gear ratio, final drive ratio, engine revs and rolling radius of a wheel as im having mega trouble with the maths.

Try a gear ratio of 0.86, final drive of 3.6, engine revs of 4500 and rolling radius of 187cm as i know what these should make.
