Hello. Apologies for rehashing a topic that has been discussed quite a bit over the years. But wanted to get some feedback on tire size compatability on the M2CS from who have success running increased tire sizes.
I want to increase tire size with the following criteria: - m2cs - Absolutely no rubbing - stock m2cs rim - stock suspension - can use spacers - no camber accessories Would love to get the rear to 285 or 295 but those sizes are usually limited due to the front limitations. **would also like to get fronts to 265. Really like the stock rims on the CS and want to weigh my options with them oppose to ‘upgrading’ the rim. |

You can run most 295's on the rear without rubbing if you're on the stock suspension. Of course, this is going to cause your handling to be a bit weird because the front is a 245. You can increase the front to a 255 without much issue because the 245 star spec PSS is about as wide as a 255.
You really need to find the tire you want first, as it makes a huge difference. If you're looking at a 285 PS4S it's nearly the same size as the 265, but a 285 888R will be vastly wider. I'd also do a google search for Bimmerpost max width on stock wheels, as all F87's have basically the same fitment, and many run 295's on the rear without issue. |

I ran 295/35/19 on my stock M2CS wheels and even run that tire on H&R coils and had no issues. Up front I was on the stock 245’s

I would like to change the cup2’s of my M2cs, with PS4S. But I can not believe the above mentioned sizing differences. Mphatic, have you seen those tyres side by side? Because 245-265 is the width of the tyre in cm… If it is 285 ps4s, it should be 2cm wider than the 265 pss. (As far as I know, star rating only changes the compound of the tyre, therefore characteristics of it.) |

None. It's perfectly legal, and normal for a tire manufacturer to put 245 on the sidewall of a 265, and they do, to cheat, for racing. 1. Go to tirerack.com 2. Pull the tires up side by side and look at the TREAD WIDTH 3. Win |
