Tire Recommendations for 20" HRE Wheels
I want to get some tires for my new HRE wheels.
Sizes are:
20x8.5 = 255/35/20
20x10.5 = 285 or 295 /30/20
Tires I am looking at are Pilot Super Sport
I guess the only question is if I should get 285 or 295 rears.

Did a calculation and looks like the 295 will fit best:
First field is stock wheels
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
255/45-18 4.5in 13.5in 27.0in 84.9in 746 0.0%
295/30-20 3.5in 13.5in 27.0in 84.7in 748 -0.2%
285/30-20 3.4in 13.4in 26.7in 84.0in 754 -1.1%
255/35-20 3.5in 13.5in 27.0in 84.9in 746 -0.0%
I will order the 295 rear and 255 front
