My 245/40/18's rub BAD!
 

Just on the passenger side though! I had to much positve camber and fixed that so it just barley clears. But looks as though the subframe might not be centered just right cause there is about 3/8" or so more clearence on the drivres side than the passenger. The wheels are 4.75" bs. I now wish I would have gone with 225/45/18's front to strech the tire a bit like my 275's on 18x10's in the rear.

how wide is your front rim?

18x8's
