I read on here somewhere that BMW states that a max difference of just 1% in tire diameter is allowable. When you do the math, that can be difficult. ie. 25.6 in. front and 25.7 rear is ok, but a 25.8 rear is greater than a 1% difference. Just curious, since I just got my first xi, is anyone nunning a slightly larger than 1% difference and have you experienced any trouble???
