295?
From what I see here 285 is "the perfect match" . http://www.willtheyfit.com/index.php...=10&offset2=32 What is the tolerance between front and rear? Is it 1% or 3%? Another question - how long do you drive on this setup ? No issues with the drivetrain? Last edited by Wlodi; 04-21-2017 at 09:43 AM.. |

Between the responses from upstate650 and I, you should be able to understand that the 255/295 is absolutely perfect. Now... If you go 285 you will need to go with the 245s. I have already told you I have xdrive, what size my wheels and tires are, and that the fitment is perfect. It's your call with what you do. Upstate is a smart dude and was very helpful. He pointed me towards the 295 and 255 set up and I am incredibly happy. Trust him.

Look, you can use whatever you want. I'm just telling you, based on experience, aesthetics, and science, that 255/35 295/30 is the perfect set up for the M5 wheels on an x drive 6 series. Good luck with whatever decision you make.

Thank You all.
Im asking because I bought wheels from a guy who was selling them because he damaged his drivetrain (I think he used M5 tires) and on the other hand Deda in this topic said he is using 245/275 wheels which I have already bought and im just thinking whether I should replace the back at the seller before putting the 343M on or not. |

you can use 245/275 set up. They will work, but they will look a little stretched. they are designed for an 8.5" front wheel and a 9" rear wheel, not a 9" front and 10" rear
The stock M5 setup is 265/35 and 295/30 - you cant use that setup without switching out the fronts for 255/35.

I am just amazed that BMW recommends using tire sizes that are not best for the xdrive. ( I mean that even on 8inch front/8,5inch rear the 245/275 setup wheels is do not have the same size - 0,9% difference between them while 265/295 is 1,3% and it damaged the xdrive)
I guess I have my answer |

Went for the 245/275 in the end anyway.
I could not find anything in good pricing in 245/285 setup. Stayed with Michelin PS4S. In the xdrive the front tires get used faster than rear so overtime there should be no issues. Looking at the wheels I do not see any stretch. |

stay away from curbs. You have no rim protection at all!

Sorry to bring up an old thread, im a novice when it comes to wheels/tires fitment. I just recently put a set of M5 343M wheels and tires onto my 2014 640i Xdrive F12. I only drove about 30miles, and the rear rubbed twice on certain bumps. Tires are Michelin Super Sport Cup 2's, in 265/30/20, and 295/30/20. I saw that some of you recommend the 255/35/20 and 295/30/20 setup as a perfect fitment. However, if I go with that, should I expect the rear to continue rubbing?
I was looking to order the Continental ExtremeContact DWS 06. If the 255/35 and 295/30 is expected to continue rubbing, is 245/35/20 and 275/30/20 my next best option for fitment and to avoid xdrive issues? Thanks in advance. |

Cup 2 tires are super soft, right? if you put any kind of miles on your car, they will wear down quick. Based on other's experiences, you must be just touching at full suspension compression. With some tire wear, you will likely find they no longer rub. Next time, use a different tire. By the way, the comment by wlodi in a post above yours that front tires wear faster than the rears on a 650 x drive is dead wrong. The rears wear at least 2 times faster on tires I have been using. Consequently, I think your rubbing will disappear with time.

Appreciate the info. The Cup 2's came used with my used purchase of the wheels. So they're not new. I was hoping i'd be able get some mileage out of them before having to replace the tires... and yes, theyre really soft. Previously owner used them for the track. The rubber on them is pretty chunked up, aside from the rears. I just dont want to spend a wad of money on 255/295, if the rear is just going to continue rubbing. The bumps I hit werent even that horrendous for NY roads. So i'm trying to decide on 245/275 or 255/295, unless I can swing 255/285 as an option without issues. Any thoughts on that?

The 245/275 setup would look stretched on 9 and 10 inch wheels. I wouldn't run 255/285 on an x drive vehicle. Look up the size difference to see what you think, but also remember the rears will wear twice as fast as the fronts, increasing the difference

A 285/30/20 is only 26.7" tall, so you are starting out with a difference of just over 1% when the tires are brand new. Tread depth is 10mm. At half wear on the rears, the tire will only be 26.3-26.4" tall. If the front are wearing half as fast at the rears, the front tire is now 26.8-26.9" tall. The difference is around half an inch, which is approximately 2%. The generally accepted limits in tire height difference for the x drive system is 1%. But this applies at every point during the life cycle of the tires. So if you start out with a 1% difference, you need to know what will happen to that percentage over time. On the 6 series, the height difference will increase over time because the rears wear faster than the front, and on the setup you are using the rear is already the smaller tire. To answer your question, a 30 mm difference is roughly 4% on these cars, which is 4x what BMW recommends, and would be very bad for your X drive system. Switching your rears from 285/30 to 295/30 won't reverse any damage you have already done, but it will work fine on your car and will not cause any further damage. I've run through 3 sets of rears and one set of fronts on my car with 255/35 front and 295/30 rear with no issues.

If your intention is to make a permanent switch to the 343, but you will run the tires on the 373 wheels briefly until you get them, I would go with the 295/255 setup. The rears last approximately 8-10K miles depending on the tire and usage, so take that into consideration with the timing of your wheel and tire purchase.

yeah I have been wanting to switch to 245/285 or 255/295 setup, like upstate says, its exact same rolling diameter, but it just boggles my mind what did BMW engineers have in mind when they made the car 245/275 from the factory, did they get a better price in that size or what?

Upstate you are the man, this is a super helpful thread.
I have a 650i gran coupe RWD and looking to buy M5 601 wheels. I assume the 255/295 will work on my car... The only concern I have is that the 601 wheels are slightly wider than the 343's Any truth to that and would that tire setup work for my f06? |

I believe it will fit the 650i Gran Coupe nicely. I'll have to do something with my spacers now |
