Hello, I'm new here- only my second post. I have a 2014 M235i with stock suspension. I am looking to replace my stock wheels and want to go a bit bigger and with a black color wheel. I don't mind the staggered setup, so I am about to purchase Apex EC-7 in black as the following setup:

F: 18x8.5 ET45 - 235/40/18 Michelin PS4 tires
R: 18x9.5 ET58 - 265/35/18 Michelin PS4 tires

I am OK with using spacers, but really don't want to do camber plates or roll the fenders.

Does anyone out there have this exact setup or something close to it? If so, any rubbing or other issues?

Thank you all in advance!

This is a rear-only perspective. Below you'll see the specs of the rear tire you're considering and the rear tire I'm running (at the track only).

I'm using an Apex ARC-8 rear wheel in 18X9.5 ET58. I also have a 5mm rear spacer, a very mild fender pull (it's not noticeable to me that it's been pulled), and I'm using the car's as-delivered components to effect the rear camber of -1.6°.

Note that I'm running a different rear shock than your OEM unit, and the purpose of what I did with my car was to enable improved street performance as well as effective track performance.

I'll be the first to admit that I'm no expert in these matters (i.e., all of my work has always been done by qualified race shops), but what jumps out at me in the data below is the section width. That is, you're looking at a wider tire than I'm running, and so compared to what my shop did for me you might need a greater fender pull and/or a greater amount of negative camber to fit the tire under your fender.

There are threads on this site detailing the fitting of 265 tires in the rear, and I encourage you to search for them to see how those fitments were effected.

FWIW, the constraint we have in fitting wider wheels and tires is the major limitation of our cars. Good luck with your upgrades!

dradernh, thank you so much for your reply. Can you tell me how you were able to use the car's as-delivered components to effect the rear camber of -1.6? Also, how were you able to get 255s on the front? Thanks again- so helpful!

The shop told me that the car came with adjustable rear camber, and that's really all I know about it.

The front has a fender pull (again, not really visible, at least to me), negative camber of 1.9, and Koni struts. Also, the front drop is 1¼" and the rear is 1".

Here's what it looks like:

I have an M240i with the exact same wheels/offsets, but needed 5mm spacers up front in order for the wheels to not hit the struts. I also have 5mm spacers out back and am running 265/35/18 PS4's. They clear just fine! Wish we could do 275's, but that isn't happening. Still on 225/40/18 (PSS, not P4S) up front, but will be going with 235's when they're done. For reference, I'm on Dinan springs and bumpstops.

Thanks so much for your response. Do you think your springs and bumpstops change anything? I would be on stock suspension. Also, do you think that you will need to make any additional modifications when you put the 235's on.

mjs597 Hey, I don't know if you're still searching / in the market for EC-7s but I can share my setup, experience and recommendation with you.

Basically I can share the three stages I've had with the Apex EC-7's on the car defined by stock suspension and RE71s, post dinan spring install, and finally post MPS4 mounted.

Apex EC-7's
F: 18x8.5 ET 45
R: 18x9.5 ET 58

1. Stock Suspension Setup

Spacers
F: 5mm
R: 10mm

Bridgestone RE-71
F: 225/40
R: 255/35

Comments: No problems at all with this setup on stock suspension, but I had spacers on hand to prepare for the dinan springs I had sitting in a box. I wanted to go for a more flush / filled wheel well look so these worked out perfectly.



2. Post Dinan Spring Install

I upped the spacers to 10mm at the F and kept the R at 10mm with the same RE71s.



Comments: No problems here again thanks to the 225s at the front.

3. MPS4s mounted to same wheels and spacer setup post dinan springs.



Michelin Pilot Sport 4S
F: 235/40/18
R: 265/35/18

Comments: This is where I ran into rubbing. With the 10mm spacer at the front (effective ET35) and the newly mounted 235/40s, I was rubbing at the front fender on large dips and undulations in the road. At this point my options were: back down the spacer to a 5mm or 7.5mm, or roll my fenders. Ultimately, since I liked the way the front was sitting visually, I rolled my fenders. Rubbing is mitigated significantly with rubbing only occurring in the worst situations (think bumps that you definitely should not be driving over at speed). I think the only change I would make about this setup would be to back down the rear to a 7.5mm spacer for aesthetic purposes only. It doesn't stick out at all, but I'm pretty finicky about visual stance and aggressiveness. '

Normally, for a 235 and 265 setup on dinan springs, I'd recommend:
F: 18x8.5 ET45 - ET45 allows you to play with spacers rather than be stuck with a lower offset you can't change. The sweet spot without rolling your fenders would be using spacers to achieve ET38-42.
R: 18x9.5 ET58 - Visually I'd recommend spacers achieve anywhere between ET48-52

Hope this all helps! I'm way more active on IG / FB via M235/240 group. So if you can find me on either I'm happy to share more pictures.

Good luck!

To add to that ^^

I am going to run below:

Apex EC-7's
F: 18x8.5 ET 45
R: 18x9.5 ET 58

MPS4S Tires
F: 245/35/18
R: 265/35/18

Spacers
F: 2.5" hubcentric spacers
R: 5" hubcentric spacers

Any more inwards at the fronts, and you are too close to the strut. If i have any rub in the fender lining, ill give it a nice push. I know someone running 18x8et43 on MPS4S 245/35/18 in the fronts with no rub at all. The 8.5" width wheel will add some chunk to the same tire, thus im choosing the 2.5mm spacer over a 2.

Rears, no worries there. Apex recommended 5mm all around but with 235 fronts as the constraint.

Thank you so much for this info Clint! This answered a lot of my questions! I finally went ahead and got it done. I ended up with Apex EC-7's F: 18x8.5 ET45 R: 18x9.5 ET 58 and MPS4S Tires F: 225/35/18 R: 255/35/18. I am attempting to post a picture.

I'm thinking of some spacers for the rears to push the wheels and tires out a bit.

APEX told me 5mm all around. That will be very safe for 235 fronts and 265 rears.

I did not buy a M235i to be safe. I would go more daring doing a 3mm on the fronts and 6mm spacer in the rear. Get a nice hubcentric spacer with some slots for weight loss. Also, find yourself some quality extended lug bolts. I'm going for 245/35/18(F) & 265/35/18(R) on MPS4S

I'd be careful with the 245 fronts even with the 35 sidewall - plug it into willtheyfit.com against my 18x8.5 ET35 235/40/18 and make sure they clear both fender and strut side against other verified forum / facebook fitments you've seen. Ie if we know that 235/40 8.5 ET 45 hits strut, but ET42 clears strut and ET35 same tire hits spacer, you'd want to be sure that your measurements fall right in that sweet spot of 235/40 ET 38-42. Good luck!

No problem! I was really adamant against any stretched tire fitment, so i was really pleasantly surprised about how meaty the 225 and 255 RE71s looked. I was obsessed with getting MPS4s on and getting as much meat as I could fit under the fenders, but to be honest, The 225/255 RE71 was perfectly acceptable to me as it was in terms of visual fitment / flushness. Plus they're really an amazing tire. Handling-wise on the street I can't see the 225/255 to be any worse (if at all even) than the 235/265 MPS4S.

How is the fitment? spacers?

Fitment is perfect, no rubbing at all. No spacers yet.
