3500 rpm at 75 mph. I have 215/40-17 tires, though.

JCW and non-JCW in any given year with the same size tires will be the same; same gearing...

From MINI2, just solve the equation for R

G = 3.126 for 05+ cars

S = R * 60 * 3.14159 * (W * P / 100 * 2 / 25.4 + D) / 12 / 5280 / G

R = RPM of engine [4750 Diesel - 6750 all other models]
W = Width of tire
P = Profile (aspect ratio) of tire
D = Diameter of wheel
G = Gear Ratio
