Hi Everyone, I have a 2004 325i and I want to get the widest (225/50 R 16 92 W or 225/50 ZR 16) all-season performance tires but my BMW manual restricts that to only summer tires, do I have to go by these "recommendations"? Is there something different about a summer tire and all-season even if the tire dimensions are identical? Also, someone recommended 225 on the rear wheels and 205 on the front. Thanks guys!
