Will I got 17 X 9.5 with 5" of backspacing. Simmons said they would fit and others have said they fit on their cars but on my car it rubbed on both sides. I went with centerline rims who said they would rub I didn't listen. The rims don't hit but the 275/40 are up against the frame. Went with a 1/4 inch spacer and it made a big difference. Haven't driven it yet but will post results if you guys are interested.
