I was considering all of that, but I've just spoke with my local wheels dealer and they recommend going for a 20" set. They say that non-RFT 21" tires could damage the xDrive system. I'm not really sure what to do at the moment .. |

That's just the info I was searching for. Thanks
For the size I was going with 255/35/21 and 295/30/21, the overall diameter difference of front vs rears is 0.2%, which is okay. When comparing the overall diameter of factory 20" wheels to the 21" I was planing to set up, the difference is +6%. The 255/30 and 295/25 are closer to the factory setup, +1.2% difference. Not so sure what to get. I don't like the stretched look, not my thing, but I really like how the 21" looks .. |

See attached my winter setup on my M550I, this never rubs Fronts 245/40/20 on 9" wheels 30mm offset. Rears 275/35/20 on 9" wheels 30mm offset Btw I mounted the 275/35/20 on the front to see if it fits and it fits but I didn't drive on it though. I wonder if it would rub when you turn.

Depending on your wheels setup I can recommend different tire setups. If you get the oem wheels I would do one of either setups since they come in 8” wide fronts and 9” wide in the rears. For OEM wheels Increase the profile size +1, which is what I’ve done. 245/40/20 recommended wheel width is 8-9” 275/35/20 recommended wheel width is 9-10” Or increase the width +1. It’s a little bit wider than the recommended wheels but some members have done it. 255/35/20 recommended wheel width 8.5-9.5” 285/30/20 recommended wheel width 9.5-10.5” You can go with wider tires +2 If you get aftermarket wider wheels, you can go with 9” fronts with 25-30mm offset and 10” rears with 38-41mm offset. 265/35/20 295/30/20
