Coupe "18" aftermarket tire size

After having lost 1 "19" rim it's back to the drawing board to get new rims/tires. Just thought I get rims+tires while I need new tires cause treads are 2/32.

I'm looking at aftermarket rims and saw a few that I like with size as F:18x8.5, R:18x9.5 offsets are +35mm.

I'm not good with using the calculator on this site, so will someone help me find an ideal tire size to go with them, that would give it a somewhat aggressive look, but won't interfere with the speedometer and such. Will 275/35/18 work in the rears? Thanks and will be lowering it later on.

To keep the speedometer the same, you would need to find a tires with circumference of approx 84" or diameter of 27". So now it's just a matter of preference of how stretched/wide you want the tires to be. If you want 275, then the sidewall needs to be 40. I personally would get 245 to 255 for 8.5" and 265 to 285 for 9.5".

Putting 245/35/20 on front and 285/30/20 on back. Putting BFGoodrich g-Force Sport COMP-2 on either TSW or Niche wheels.

245/45/18 & 275/40/18 puts you pretty close to OEM with your rear at -0.07% smaller than the front
