Someone chime in please. I should be good to go with a 255/35/18 in the rear. I'm running apex arc-8 et38 (18x8.5) all around. Fenders are rolled and pulled and shaved all around. And in the front I'm running -3 degs of camber. I think the front will be fine just the rear I'm worried about. Last alignment it was -2.3 degrees in the rear but i raise the car up since then I might have to lower it again to get that correct? Car is on Kw coils with swift spring conversion and 7 inch spring up front to clear tire from the adjustable perch.

I can fit a 255/35 R18 on mine with a ET40. I would not see why you can't do it.

In the rear? Are you rolled?

Yeah. Rolled and slightly pulled. I tested them on before the engine failed that day.

The 18x8.5" ET38 is quite aggressive for a squared fitment on the 1-series, the rears would need the fenders modified, likely pulled, as that is what's already needed for the 17x8.5" ET40 with 255/40/17 tires. We have not been able to test this in person or gotten any customer feedback on this fitment. Any particular reason you wanted to go with this low of an offset instead of the 18x8.5" ET45 squared? Our 18" 1-series specific wheel is the 18x8.5" ET45 ARC-8, which is an easier rear fitment in the rear due to being in 7mm more inboard, but even at this offset rubbing can occur, so a rear fender roll is still recommended. The 245/35/18 is the recommended tire size. A 245/40/18 is far too tall for the car and would cause tire rubbing on the fenders. The 255/35/18 tires can fit up front on the 8.5" ET45 wheel but a thin 5mm spacer may be needed in addition to camber plates being needed for all these listed fitments. Using a 255/35/18 would already be very aggressive on the rear at that offset, so heavy fender rolling and possibly pulling is needed even with this higher offset wheel.

I got them to fit! No problems what so ever! Thanks again.
