So if you stay within 1.3% from stock you should be fine.
If you ask bmw they wouldn't recommend anything but stock. Lol
It's weird how Bmw only knows the numbers that computer shows. Most likely wouldn't recommend anything else but stock tires.

If I bought 20” I was going to try R888R in 285/35 front and 305/35 rear. This makes me reconsider since it is 1.8% difference.
Think I will get 21” and roll 285/30 front and 295/30 rear at 1.1% to match stock |
I think this expert is telling us the car is set up for a 1.1% difference anyway, so it's the deviation from that which is important.
So a 1.8% difference overall isn't actually much of a difference from OEM, if you know what I mean.
At least that's my interpretation of the original comments...
