I have a set of 15 x 7 alloys, optional with the BMW E36 328i. I'm currently running Michelin Alpin winter tires, but will shortly change them for a set of summer tires. I want to buy Bridgestone Potenza S03 225/50/15 instead of my current 205/55/15 Michelins. Will this be beneficial with a 7" rim or am I wasting my time because the rim might not be wide enough to justify the upgrade? Thanks all in advance.
