I don't think this is right but is it : (engine rpm) times (transmission gear ratio) times (final gear ratio) =(axle rpm)????

A) Gear for X Mph @ Y Rpm
I know what each gear ratio is and can set them along with the final. I also have a
certain amount of say in tire size and compound.
The tire's rolling radius, if say a 335/45-17 would be half of the rim's diameter
(17/2) + 335 milimeters converted to inches x .45 (the aspect ratio). The speed
then in mph at a certain rpm is given by
((rpm)(60)(rolling radius)(2pi))
--------------------------------
((gear1)(Final gear)(63360))
I use Microsoft Excel to make chars where the x-axis is mph and the y-axis is
rpms.
