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 .. |
I recommend 245/35/21 and 285/30/21. Or if you have wider wheels and correct offset you can get away with 265/30/21 and 305/25/21. Don't use 255/35/21 in the front, it rubs sometimes lol I love the way it looks but hate it when I hear it rub!
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.
