If it's any help, here's my spreadsheet for calculating speed based on RPM, trans ratio, axle ratio and tire diameter. You can edit any of the green background cells and the speed will show in the yellow cells.

Thanks GFaRT, that is a handy little title work’sheet’. Saved into ‘notes’ on the phone.
Years ago when we really only had the 1:1.0 output it was a pretty quick study, now with many overdrive ratios and a large variety of tire heights, a little short cut is welcomed. Thanks guys.
