About rims and tyres
I bought the 320i (E90) 10 months ago. I have sport suspension (Dynamic pack) with 159 rims (158 is stantard with this package). Would like also to put the 162 rims but there are 2 main reasons that I didn't go through tat option. First you have to consider about the extra cost for the rims and secondly the cost for the tires (17'' to 18'' rims have way too far different prices). You have to think also that the rear tires are 255mm in width with 162 rims in comparison with 225 with 158/159/160 rims. Finaly as you can see I live also in Greece. I love 162 rims but the greek roads are tragic.
