And 255/35/20 isn't an OE front tire size anyway. The main thing from I was trying to point out is to try and achieve under 1% difference in rolling diameter.
But I did also just checked the OE 20' size and the 245/35/20-275/30/20 is also a -1.1% different in diameter so I guess in the grand scheme of things if BMW runs that then its fine. When I researched this xdrive staggered before I would always find the rule of under 1% of rolling diameter difference. |
Appreciate your thoughts. Given OEM is -1.1% I guess there is just a bit of leeway with it.
