I have a 2009 A5 that I just got new 20x10 rims for. From what I can tell, the best size for these rims on this car are 265/30 20's. I'm having some difficulty finding an all weather tire in this size. I can find winter and summer tread but no all weather. Here's my question. Can I go up to 275/30 20's on this vehicle. I know the rims can take them but my concern is that the tire might look a little jeep like. Anybody out there have any thoughts or know any body with this rim/ tire combination?
