I'm running 18x9 with a 20mm offset with 285 70 R18's, I think 18mm would proly work but it gets real tight on the tuck! brand of tire, side tread, actually tire size etc would all play a huge roll. Long story short I think they would work.Looks good! Do you have a view down the side or top of the wheel well? I'd like to see how much a 9in wheel with a 25 offset sticks out. XD makes a 17x9 +18 but I think that would poke/rub too much with a 285/75. Maybe some light strategic hammering and fender work would make them fit?
