9.5 +22 & 10.5 +35 are for stock tire sizes...which sucks because they end up stretched more than the already stretched factory fitment. ANYTHING wider and you will rub, it's commonly known. Now, I will say that because there is no tire sizing standardization that some tires run wider and some skinnier, so there's that, but in general, with the FI-R, you're going to need stock sizes. Most all of the companies that make sizes specific to the M2 are now doing front 9.5 +25 to 28 & rear +40 to 44 to accommodate the 265/295 that a lot of guys seem to want. |

Vredestein Vorti are fine https://f87.bimmerpost.com/forums/sh...2&postcount=14 Bridgestone RE71 are fine https://f87.bimmerpost.com/forums/sh...&postcount=211 Michelin PS4S are fine https://f87.bimmerpost.com/forums/sh...9&postcount=25 https://f87.bimmerpost.com/forums/sh...3&postcount=46 Instead with 265/295 you will have problems with this setup. |

Your second link doesn't say anything about rubbing. Your third link is suspect, as it mentions no rub at all. Your fourth link describes it better, some rub with nearly stock size tires and a drop. I'm not going to argue with you about it, but what you have here is a case of people a.) not willing to tell the whole truth to safe face, and b.) driving their cars like a grandma on perfect streets. I'm a huge FI-R fan, and will have a set one day, but I have no need to lie to protect my investment, and I don't drive like a damn grandma. When I get my set you can bet I'll be telling the whole truth about it, camber at max adjustment and all. EDIT: From the fourth link, the PS4S in the 255 size is nearly identical to stock. Stock 245/35 has a 8.8 TW & 25.8 OD PS4S 255/35 has a 8.9 TW & 26.0 OD The rear is also very nearly the same. Stock 265/35 has a 9.4 TW & 26.3 OD PS4S 275/35 has a 9.8 TW & 26.6 OD Last edited by VisualEcho; 05-03-2020 at 07:26 AM.. |

PSS 245/35 = 8.8/25.8 RE71R 255/35 = 9.3/25 PSS 265/35 = 9.4/26.3 RE71R 275/35 = 10/25.6 The 71R is one of the best drive-to-and-from-the-track tires ever made, but won't last long at all on the M2, and run super wide, so are definitely not suitable for FI-R sizes unless you have the suspension to go with it...and the coin to replace the rears ever 8,000 miles. |

It would be muuuuch easier if all tires of the same size had the same width

OMG I have wished for a standardization since I first started selling tires in 1996, but it's just never going to happen. Thankfully we have places like tirerack that give us the specs of most tires so that fitment nit-pickers such as myself can buy tires with confidence.

Those Richland Forged wheels say designed in USA and made in China. I wonder what "designed" means, I am not taking a stab at them but those wheels look almost identical to BBS FI-R's without the spokes that have the machined openings for weight savings.
Anyone weighed these Richland wheels yet? |

So it ALL depends on the exact specs of the tire you're buying, as some tires run skinny for the size, and some run wide. A lot of it is the shoulder shape, so an all season tire with the same specs, or even a bit more may be ok when a true Summer tire will not (this is because the Summer tire has a squarer shoulder). And a semi-comp tire, like a RE71-R? Forget it. They make their living lying about their specs so people can get an edge at the track. |

Where did you find they rub in the front with 245 tires? |

Stock tire specs are: 245/35 = 8.8 TW & 25.8 OD 265/35 = 9.4 TW & 26.3 OD Your specs will be: 255/35 = 8.9 TW & 26.0 OD 275/35 = 9.8 TW & 26.6 OD As you can see, the 255/275 combo isn't hardly any wider at all, it's just taller. However, since your wheels are 25mm wider you may not have an issue at stock height. Buy them and let us know. |

I have the FI-R on my M2C, stock height, stock tires, no rubbing.
Not sure why some are claiming rubbing at full lock. I am going to ratchet the car down and compress the suspension fully whenever I find the time to do it, then I'll really see if it rubs under full compression as well. Also will be able to measure how much room there is to run a larger tire sizes with it. |

In either case, I'm not sure the type of rubbing that is being experienced will cause any issue. However, buying taller tires, lowering the car, and then using it as a track toy might cause a different type of rubbing, one that could cause damage. |

There are two options for the front. The 9.5 inch 19' ET26 should not have any rubbing issues at all, it's virtually identical to the APEX wheels for the M2C. Particularly on stock tires as they will be very stretched. The ET 23 would also be perfect for track wheels as they will clear the suspension perch on aftermarket coils (its effectively the same as running the ET28 Apex wheel with a 5MM spacer which they recommend on some applications).
The rears appear more troublesome at ET35 (Apex is ET40) but I think you can get away with it, particularly if you are running stock sizes. This guy is running the aggressive offsets on his M2C and they look fantastic, I copied one pic which shows the offsets on the car but this thread has a ton of pics. Looks like he's running 255/275. https://f87.bimmerpost.com/forums/sh....php?t=1712677 If I need another set of wheels, it will be be between these and HRE FF11.

I am certain an M2c will rub in the front, running that same configuration and if the car is even remotely lowered. |
