I'm no expert, can tell u now they won't fit properly though. You will need to at the very least roll the guard and stretch tyres. If you don't want to stretch tyres then you will need some camber, around -2.5 or a guard pull to bring em out further.
I agree. I've got 10" rears with 295/30's on a +38 offset and about -3.5° camber to make them fit. I also lipped the guards in order to not scrub on hard corners when the rear is under max load. You also need to make sure that the inside of your wheel doesn't interfere with your tie rods when hicas is working.
Well your not trying hard enough. A 38 offset should fit a 295/30/18 snug as with the lip rolled and less than 1deg camber. A 35 offset will need a little more camber. I run -.05 on the rears of mine and they're fine with a 295/30/18, and I've run them flatter on a 2 seater with a 41 offset, with some sledge beating of the inner wheel well.
