So i have ordered a new M2c that will be delivered soon and I have come across a setup of a BMW 763 setup from the M4CS with dimensions 275/35-19, et29 9x19 and 285/35-20, et40 10x20.

Will there be any problems with the front?
I have tried to find info about this and what I have found it shouldn't be any problems but I wanted to ask all the professional here first

I feel you may have a typo and mean "30" instead of "39" for the sidewall? I have never heard of a size 39 sidewall lol

I don't know for sure - I think some guys have tried 275s on the front, but there might be some rubbing when in full lock. There was a thread talking about it around here somewhere.

I am pretty sure you will be fine with the 285s in the back...I think some were even trying 295s....

I'm guessing it will rub with 275's on a 19 wheel. I was able to fit 275/35 on my M2 but on a 18" wheel. Ideally you would run a 255 or 265 front and a 275 or 285 rear.

Better off with the 19 inch 763 set for lighter weight and guaranteed fitment.

You can easily run 255/35/19 and 275/35/19. You can also try 265/30/19 and 295/30/19.

It’s a shame Michelin doesn’t make a PS4S in 285/30/19.

Thanks for all the answers, im thinking that in the worst case that I can use the original 265/35 rubber that the car is delivered on and use it in the front?

[jdub486]

265/35/19 could rub up front. It’s half an inch taller than a 245/35/19.

255-35 & 275-35 is the max of you plan to lower, 265-35 & 285-35 would be way too big and thick of a tire, doesn't look good, unless you go down on sidewalk which is 265-30 & 295-30, but then again, the wheels won't be wide enough to handle that width. Just my 2 cents

Why not the 19 F/R designed for M2? Should be cheaper also...

The M2c staggered stock fitment is two sizes larger in the rear when compared to the front; 245 F, 265 R. IMO if you go with wider tires you want to keep the same F/R ratio to maintain the cars handling characteristics. For example, 255 F, 275 R.

The price is really good and it's 2nd hand.

I have the both 245/35 and 265/35 that I can use on the front if needed

I found the same setup that I intend to use and have the car lowered☺️

The claim of using 265/35-19s up front with no rubbing goes against many people's experiences in this forum. The larger diameter is the issue here, not the width.
