[Orange fever]

you should be fine, i was on 245/35/19 and 285/30/19 (Hankook)
i think 255 front would be perfect

They said to use stock tires but I have a feeling my stock Contis would look too stretched! So I'm thinking of going with 255x35 front and 275x35 rear. What do you guys think? Should I expect any issues? Car is stock height.

You should be ok with those sizes since you have the OG. M2C owners reported more trouble fitting 255s on the front.

Also the difference in added offset in the front and rear is desirable. Stock sizes typically need 5mm more in the front but it also depends on camber. I used to run 10mm front, 7.5mm rear and it was perfect. After I added some camber to the front (1.85) I had to bump up the front spacer to 15mm to keep it looking consistent.

I ended up going with the stock size tires and it looks pretty good!! Now all i need is a lowering kit !

I can share a bit there as well. Don't believe all the hype about the Dinan HAS. It got praised as being more comfortable than OEM. No it's not. It's not much worse but the spring rate are higher. The ride quality is about the same as significantly cheaper H&R springs but you can't fine tune the ride height.

Just one question for those of you guys, who experience some rubbing:
Do you know the area of rubbing? Front/back, where exactly (inside/outside)?

I'd like to know that as well. I have a feeling it's most common between the outer edge of front tires on full turn in which rubs against the front surface of the front fender well lining

Running 12.5mm front and 10mm rear on KW V3. Here's the fitment:

Looking just perfect!

Sorry, I have to specify my question. There are two kinds of rubbing.

First one happens while parking when turning the wheels. That happens at the wheel arch liner towards the front (where the ventilation grid is lacated at). That's due to the thickness of the tire. E.g. it occurs at my car only with my winter tires, which are much thicker compared to my summer tires. But that's nothing to be worried about.

What my question was about is the second kind of rubbing while driving. This one happens at my car, even with thin summer tires, when there are some special kind of bumps (long deep bumps at highways for example). And I guess then the tire touches the part of the wheel arch liner where front bumper and front fender are linked. When you take a look at your front wheel arch liner, there is a spot which goes a little bit down, hard to describe, just like a bump.

Oh yes you're correct. That second scenario would be more troublesome I imagine. That one is probably from a lower suspension that's too soft so it allows for enough movement so tire hits the fender lining or even worse the edge of the fender itself it the tire is sticking out beyond the edge of the fender... if I remember correctly there was someone who had a horrendous crash after a rear tire caught the fender at high speed... that would be worst case scenario

Found the thread of the crash:


Pre-Lci Fender Issue? https://f87.bimmerpost.com/forums/sh....php?t=1481781

[M2C]

Oh whow, that's horrible. I guess this guy had more than 10mm spacers so that the tire hit the edge of the fender.

The spot that I mean is inside the wheel arch liner. Here is a picture where I marked the two possible spots (not sure about which one is the one which gets hit):

So I have 245/265 PSS dropped on KW HAS and never had any rubbing, even with passengers. 2018 M2 F87. Just put new tires on 255/275 P4S and I'm getting rubbing on the right rear if I hit a dip. Surprised. Maybe will try to swap out rear spacer to Turner 5/7.5MM but wondering if that will make a difference?

I have Burger 10mm spacers all round. Would it be bad to run Turner 7.5MM in the back and Burger up front? Can I use the same extended bolts from Burger in the rear that I was using with the 10MM with the 5/7.5MM Turner rear spacers? Sounds like if I go down to 5MM might have vibration according to the Turner web site but doesn't say that about the 7.5MM?

245/35 & 265/35?
255/35 & 275/35?

And here's why...

Thanks for this. I wonder if 5MM or 7.5MM spacers will make a difference rather than 10MM?

If you're rubbing up top the smaller spacer probably won't help.

However, if you're rubbing on the inside or outside, then it certainly will. The tire is .4 wider, which is .2 on each side, which is exactly 5.08mm. So if you were you, I'd switch to a 5mm spacer in the rear or run none at all.

[DriverDaily]

Front: Turner 7.5mm spacers
Rear: Turner 5mm spacers
Suspension: Bilstein B16 Coilovers.
Fitment: No rub with factory tires and alignment specs. Tested up to 2 people in the car and 50kg of bags on some of the worst Boston roads.

[nothingman]

I'm looking to move to 275/30 and 295/30 MP4S tires from stock tire sizes on 763M wheels and am concerned with rubbing against my Ohlins R&T front suspension. I'm currently on stock top hats and would like to add BMW correction hubs to get -2.5 camber up front. Would the increased camber cause the tire to lean in and be more likely to rub the suspension?

Anyone know how I can measure to know if I will need spacers to help prevent rubbing? I'm not looking for spacers any larger than necessary as the wider tires should poke as much as I'm looking for. I wonder if I can get away with Turner 5mm or 7.5mm?

Here's a pic of the clearance I have now:

[DriverDaily]

Raised to 605mm rear, 600mm front. Still running Turner's 7.5mm front and 5mm rear spacers.

Looks good. I eyeballed the ride height when I did my KW's. Ended up with 590 front and 607 rear. The front sits a bit too low for me so I plan on raising it about 10mm.

Did you run into any alignment issues when you raised it? I, assume it's going to throw something out of whack, just curious how the toe was affected.

[VisualEcho]

Recently dropped the car on MPS. All the way down on the rear, and 3.5 threads showing on the front. This gave me a 19mm drop in the rear, and 25mm drop in the front. Spacers are 10mm rear, 12mm front.

I'd be interested to know this as well. I have Ohlins but with camber plates. Although I think 275 may be too wide in front.

Yes, I always get an alignment when adjusting ride height. I dont remember any specific numbers but I do remember most things were in the red after we did the adjustments.

[mr_lab_rat]

The front alignment doesn't change much if you change ride height by 10mm but the rear camber and toe changes a lot.
