Shawn: I will measure bulge to bulge, but this is what I have so far. The wheels are 17x8 with a 20mm offset and I am running 225/45/17 all the way around. I had previously rolled the rear fenders to fit my 15mm offset 16" wheels with 225's, but now it appears that rolled fenders are not necessary for this setup. The car is lowered with H&R Sports/Bilstein Sports, and has no clearance problems. HTH.
