I've had my e92 about 8 months now. The last few months I've noticed a vibration that feels as though it's coming from the passenger front wheel. Its almost as if there is a hard spot on the wheel. The faster you go the more you feel it. It's worse when it's cold but I've also experienced it on some warm days. Am I likely experiencing the normal behavior of RFT's or could this be an unbalanced tire or a cracked rim? I'm going to call my dealer but wanted some opinions here first. Thanks in advance.
