Interesting, glad we are gathering more data points. The fact that the PAs are the same size as OEM is even more concerning. Mine also occurs at (almost) full lock when reversing or turning slowly.

So what's the solution here? I like the aggressive look of the wider (and slightly taller) tire, so would like to keep it even after this set of tires is done. Spacers? What would I need, like a 5mm spacer? Do you need to do front and rears then, or can you get away with fronts? I know nothing about spacers....

[Brokenbones]

I think spacers would likely increase rubbing as decreasing wheel offset w a spacer would move tire/wheel away from midline towards the fender lip and increase wheel arc at full lock.

I think.

Change tires, do nothing and let the liner wear out over time, or get a heat gun/belt sander.

Am I wrong in suggesting that, since the 437 wheels are reportedly the exact same size as the 788 wheels, the solution is to just stick with stock tire sizes?

As you know, I am on stock 788/PSS setup with MP coilover drop and 10mm spacers all around . . . and I have no clearance issues.

Yes, its the likely solution, but as others have posted on this thread, even non-MPSS OEM sized tires like the Alpins are exhibiting this issue. I'll stick to stock for next season, in the front. The wider rear tire with the wide ass is awesome.

I was just asking for a temp fix perhaps...

When I was thinking I would be staying in Michigan over the winter, I investigated various wheel and winter tire options.

I do not recall the details now that I have been in Florida for a while, but I do recall VisualEcho PM'd me some incredible insight that completely convinced me to stick with stock tire sizes.

Might be worth hearing Visual out.

I'm hardly a automotive technician, so I welcome any and all advice here, but seems even Visual is a bit stumped with this one. It's surprising that folks are reporting rubbing with even OEM sized non-PSS. I'll stick to OEM size next winter, but just really like the look of the wider tires...

Sorry if I was vague, but my prior post was with reference to the tire sizes in general, whether winter or summer.

I forget the details at the moment, but recall Visual convinced me not to deviate from stock tire sizes. If you recall, not long ago we were talking about how the M2C was 'under tired,' and discussed wider tires as the solution. This was about the same time I was thinking of staying in Michigan and looking into winter wheel/tire setup.

At any rate, do not mean to belabor the point, other than to say deviating from stock tire sizes is not as simple a matter as I originally thought. . . do not mean to suggest deviating is the end of the world either.

I've also realized it's now as simple as I thought. Apparently BMW does not want us to fuck around 😃

No kidding. I mean - 788m wheels, stock suspension, stock tire size, same tire manufacturer - and it rubs!

I was very surprised. I think heating and molding the liner might be the best option.

The Sottozero 255/275 combo isn't really wider, it's just taller. Even in the beloved PS4S it's barely wider. You really need the 265/30 & 285/30 (or 295/30) to be appreciably wider.

I had similar issues with my winter tires since I’m running 40s. It happened to rub quite a bit more on the driver side so I tried the heat gun bend method. It worked well enough on the passenger side. It still rubs but not a whole lot and not too loud. It didn’t do a whole lot to the driver side so I pealed back the liner and found the reason why I can’t push it in any further is because of the way the liner vent is made in conjunction with the radiator right behind it (outlined in red). There just no room for it to go. I thought about cutting the inside of the liner back an inch or so all the way around so there would be room to push the liner in. However, I already put a hole in the liner trying to push it in just above the vent (too much heat and pressure as well as unknowing pushing on the corner) so I decided to continue with that. I trimmed down the plastic with a dremel (highlighted in yellow) and extended the hole to then heat it up and bend it in (outlined in blue) since this is where it was rubbing most for me. I then used plastic weld to cover the hole and prevent it from bending back. Now I have zero (audible) rub from that side. If I could do it again I’d probably just cut the inside of the vent housing a bit and do the heat and bend method. May just do this on the passenger side if it starts to bother me. Hope this helps someone.

I have the exact same set up and no rub issue whatsoever.

437s

Pirelli Sottozero 3

255/35r19
275/35r19

Full lock no rub .

So there is this unnecessary ridge in the fender liner that appears to be the culprit. When the wheel is turned inward (opposite to the wheel direction in the pic), the outer edge of the tread rubs along this ridge and makes the sound

Don't sweat it bro, leave the wheels as is and let the fender lining erode, if they must..

I priced a replacement lining and they're under a $100, per side.

Just replace them if they wear out. Problem (somewhat) solved. Just don't leave the lining completely off, water intrusion might seep into the headlight LED modules but cosmetic scuffs are alright.

To the realization that your car might be just a bit different than the norm, either with alignment, or something else.

If it were me, I'd literally buy a used OG M2 liner, set them side by side, see the differences, and try to install the OG onto the car with any real changes that were made to the M2C liner. But that's because I'm a bit OCD .

Not at all sweating this, its very minor rubbing and happens mostly when I exit my garage due to the turning angle. I'm not changing anything, i'm just here more for curiosity given that my preference is that even the next set of tires (summer or winter), be a bit wider. Does seems like many are having this issue though, even with OEM size.

I literally just ordered my Alpin A4s in the 235/35/19 and 265/35/19 stock sizes and will be putting them on 788s. I saw a number of folks had no issues at all which is why I went this way. Looks like a couple folks are having the rubbing issue though with this approach.

I guess I can just pray that I do have the rubbing issue.

My humble advice is when you're replacing those winter tires, go with all four 245s, square; that way you can rotate and stretch them out, not to mention guaranteed no clearance issues.

Wider winter rubber are unnecessary IMHO, since their inherent softer rubber compound don't make for ultimate BMW handling potential anyways, so your performance will be compromise, regardless of the tire girth.

Save the playtime drifting and such for when the summers go back on.
