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
Most wheel manufacturers recommend 285/35/20 and 305/35/20
I ordered wheels that are coming next week
10" front and 11" back
Will go most likely with that tire size above.
I was thinking to go with R888R too but, friend of mine had it and said you will pick everything from the road and have more damage on side off the car from the stone/ sand
So I might go with different brand
Rear tires will wear quicker so it can be higher
