Hi guys,

I will be driving my 2013 BMW 335i xDrive M Sport Coupe this winter for the first time. I am looking at purchasing a slightly used set of winter wheels that were formally used on a 2013 M3. The rims are style 270M (18x8) with a square setup of 235/40/R18 Michelin winter tires.

I am wondering if these wheels will be a good fit for my car.

Thanks.

You're not in the right forum FYI this is for E90s. 2013 335i is F30 I think.

No, a coupe is an E92, which lasted til 2013 in USA/CA.

M wheels have a different offset, and rarely fit on non-M cars. The rears will likely not fit, although with that width they may.

Oh you're right my bad I didn't notice it he/she had a coupe.

Well, first you didn't give us enough information to allow us to speculate on an answer. Second, you'll probably have to do a trial fit to know for sure.

Since I don't have the M car in question, I don't know the offsets of the wheel, I don't know the actual width of the tire (235 isn't definitive), etc.

As stated above, the car in question is my 2013 BMW 335i xDrive M Sport Coupe (E92).

These wheels are off a 2013 BMW M3 (E92) and were sold by BMW to E9X M3 owners as part of the winter wheel package.

The rim size is 18" (18x8) ET20 with a square tire set up of 235/40/18.

Thanks

So, this is how I think about it (there's a more extensive set of explanations on tirerack.com about offsets and fitment that you should peruse.)

The biggest (stock) tire on the rear is 255/35R18. An ET20 is ~15mm pushed out compared to a stock rim (et35 or so). But the 235 is 20 mm narrower than 255; so 15-20 = -5. The outer edge of the 235 is going to be 5 mm in from a 255 outer edge.

It will fit. You may actually have more trouble at the front, but I think it will still fit.

Your math is a bit off but it will still fit. 255-235 = 20, but that’s only 10mm per side (10+10 = 20) so it will be 5mm further out than a stock rear. That being said, you can fit a 20mm spacer on the rear on stock wheels and be fine so rears will be no problem.

Front will be no problem either. I’m lowered a ton and run a 255 on a 8.5" et 23 and don’t even rub. (i have a sedan but fitment is same for coupes)
