Help choosing the best tire size

exia_m3 · 06-18-2015, 12:40 PM

The rims I am looking at are 20x9 front 20x10 rear.
After much research the tires size should be 245/35 front,
this is where I get confused 275/30 or 285/30 for the rear.

Any input would be appreciated they both are close to the base rolling diameter of the stock 18 for my xdrive non m-sport.

245x.35=85.75 front
275x.3 = 82.5
285 x .3= 85.5

then 285 /30 is the one, the difference is so small, the system wont feel the diameter difference
