265/40/18 Rear?

raptorman5174 · 03-13-2019, 09:28 AM

hey guy quick question here. This my current setup

Front 18/9 ET38 225/35/18
Rear 18/10 ET33 255/35/18

I am also running 5mm spacers on all 4 corners and currently the stock sport suspension, My question is that stock tire size is somewhat stretched out so I wanted to go wider.

Will I have any rubbing issue if I go with this tire size on the same rims? Also I just purchased a set of Eibach Sport Springs so the car will sit lower. Should I go with a 35 aspect ratio instead of 40?

Front 235/40/18
Rear 265/40/18

I have Michelin PS4S 235/40/18 and 265/35/18 on my '09 E92 with 189's. The suspension is stock and I'd suggest doing springs, shocks and struts before tires. You need to see how it settles and then the tires.

yeah that's a good thought, I was gonna put the springs on anyway before the tires. I was just hoping someone else had a similar setup

I think you should be fine in the rear. I have 255/35/19 on my rears with no problems. This is equivalent to 255/40/18.

Also my car is LCI E92, and I believe I have less space in the back than the pre-lci. So you should be fine with the 265.

But you'll have a bigger difference in overall diameter between front and back. 265/35/18 will get them closer.

thanks for the advice yeah I may run the 265/35 on the rear and the 235/40 on the front.

gonna get my suspension setup first, just purchased some Eibach Sport Springs

Do you have pics of 255/35/19 in rear? I am thinking about getting this size and can't find much on it.

Not sure about the front. It might be tight with this size. Never tried though.
