I've tried looking this up but no one seems to run 285 all around and I don't know much about fitment so could someone help me out!

I'm not sure about the tires probably going to go with pss or pzero anyway... I want to run a square setup with 10.5 on both front and rears and 285 all around. Could anyone that has seen this tell me what offsets and basically fill in the blanks to what the specs are that will not rub and fit flush. I want to run this setup on TE37 SLs 18".

I want to run this on stock suspension if possible but I might be lowering the car on kw springs.

there are a few track guys that run 295's squared and they are on 18x10.5 et27 wheels. i believe they rub a bit. 285's will likely rub as well.
different manufacturers have different widths for a 285 tire independent of the sidewall measurement, so you might get rubbing simply by using a specific brand of tire. it is that close when you're getting into the 285's. this is also why you're going to find vague or conflicting information.

35 or 30 aspect ratio makes a big difference. 285/30-18's will fit all around all day long, might rub the rear of the front fender liners a bit

285/35-18's will rub holes in the rear of the fender liners up front, and fit fine in back

Is this for DD duties or track wheels? At the track you will probably never be at full-lock except for navigating the pits, so rubbing is less of a concern.

If it's a DD, I would go a bit more conservative. So you're not playing games with spacers and adjustable ride height. It's not exactly like driving around town at 35mph will let you take full advantage of a big square tire setup anyway.

It's a DD but I will eventually take it on a track later on but my main reason for this is to have that meaty look and I just heard a lot of people think square set up is better.

Also I've been talking to one of the members here and he suggested getting 18" 10.5s all around et27 where could I order te37 SLs in those specs?

And finally could I run staggered set up on that and switch between square or staggered later on if I run 10.5s all around on wheels?

Then just get a square track/wheel tire setup at that time so you don't chew up your street tires.

Ok thanks for the advice but I still will probably go through with getting 10.5 18"s all around so where do you think I could get custom offset te37SLs? I looked it up but I couldn't find anything they were all preset and sold by other vendors.

If you lower the car and don't run camber plates you're going to run into issues. I ran a 265 35 sport cup 2 on square 19x10s. I put them on before i put on my camber plates and this was the result.

If you decide to go through with it, you want 18 x 10.5 et 27. Stick with 30 profile tires and keep in mind michelins run wide. a 275 fits a 10.5 inch wheel perfectly fine so a 275 30 18 is my recommendation. Again, if you lower the car you'll have issues. Remember, you have plastic fenders lol. Best of luck!

With stock suspension and alignment settings, I would advise running 18x10's with 275/35-18 tires on all four corners. There is a reason why this fitment is so popular.

The 18x10 (lets say with a common et25 offset) is a direct fit on both the front and rear of the car with 275/35-18 tires. The benefits are that you do not need negative camber to fit this setup under the front fenders, and there are many tire choices in this size. Furthermore, 275/35-18 keeps your overall rolling diameter in check (correct), whereas 285/30 is short, and 285/35 is too tall. Keep in mind the 275/35-18 will look meatier then 285/30-18 tires as well, due to the taller aspect ratio.

I personally run 18x10.5" wheels on all four corners, but I have the proper suspension and camber to warrant it. I also have the car sorted for track duty, as it is not my only car. On that note, my setup can also be daily driven no problem. To fit 18x10.5" wheels, it requires negative camber (camber plates), suspension with linear springs and no helper springs, and wheels with an offset of et22. If the wheels have a higher offset (like my APEX 10.5" ET27) you will need small spacers to clear the suspension.

Respectfully, your information is incorrect.

- Michelin's do run a touch wide when in comparison to other street tires, but not when you compare them to extreme summer or r-compounds tires.

- The desired offset for a 10.5" wheel is et22. Anything higher (more conservative) will result in the need for spacers to clear the struts.

- 275/35-18 tires would be recommended, not 275/30-18's.

- The car can have a low ride height no problem, as long as your fitment recipe is correct and your spring rates comply.

My car disagrees with you. And yes a 35 is ideal but not when you're cramming big wheels in the fenders. He's pushing the limits as is. No doubt a 10 inch wheel is the better choice here.

Your car was not running the same specifications. You were running a square set of ZCP wheels (which are 19x10 ET25) with 265/35-19 tires, correct?

275/35-18 tires - Height of 25.58"

265/35-19 tires - Height of 26.3"

As you can see, your tires are much taller then the proposed 275/35-18's.

Regardless of "big" (I think you mean wide) wheels being ran, 275/35-18 tires are still the correct choice. 285/30-18 is acceptable, although still a bit short in terms of overall rolling diameter. Under no circumstance is 275/30-18 advised.

No sir, referring to my track set. 18x10.5 et27.



I ran a 275 30 19 on my e46. I wouldn't run it on my track set but curious as to why you say it isn't advised?

You are a bit all over the place here. You initially posted pictures of your square ZCP setup (here, and in other threads), so I am assuming that is the wheel set that you experienced fender damage with, correct? Your damage was due to the overall height of the 265/35-19's, which I have displayed in my previous post.

Yes, the E46 M3 takes 275/30-19's, but we are discussing 18" wheels here therefore it has no relevance. Also, different M chassis call for different overall rolling diameters, so be careful when comparing one to another.

I think you were just confusing two stories. You said 18 x 10 et 27 wouldn't fit. I was just saying that I run that set up just fine. The ZCP mishap is unrelated.

Please re-read your post. You posted pictures referencing your 19" ZCP setup, which may falsely deter readers. Your 265/35-19 tires were the cause of your damage.

^ This recommendation is incorrect.

Last, the 18x10.5 et27 will absolutely fit, please refer to the photo's of my car above. I was simply mentioning that he will need to pay attention to strut clearance. ET22 is ideal, whereas ET27 typically requires 3mm or 5mm spacers (final spacer size depends on ride hight, tire brand and suspension type).

Right, and I'm saying that I don't run a spacer with that size and I clear the strut. Also define "incorrect". The ideal tire size is a 35 profile but in his scenario I think a 30 profile may prevent clearance issues. I do sincerely apologize however for "falsely deterring readers". I do not wish to be misleading in my preceding posts. LOL.

IIRC, the TE-SL has an offset of ET22.

That's exactly how I want mine to sit but I'm assuming that has suspension and camber plates because everyone has been saying you need that stuff to fit that set up.

Oh and yea I know I didn't know if people got custom offsets or something to fit perfect or do they only come in that offset?

What I am trying to convey here is that running a 275/30-18 is not a correct or acceptable solution. There are consequences for altering the overall rolling diameter. A 275/35-18 will fit just fine, and is the proper height so there is no reason to steer people towards running an incorrect tire.

Where the OP needs to be concerned, is with inner and outer clearances. 10.5" wheels will require some negative camber up front, and since he mentioned running stock suspension, this is not the ideal fitment for him to run. Hence my recommendation of 18x10 ET25 with 275/35-18's.

To be clear, you are running a square set of EC-7 18x10.5 ET27 wheels with 275/35-18 NT0-1 tires, and Ohlins R&T suspension with no spacers up front?
