"I noticed the other day on the freeway that my left front tire seems to be vibrating quite a bit more than the others and making noise. The balance weight is still intact.
Is this what you are experiencing?"
It's a vibration that can't be ignored even without sound dampening. Feels like the front wheels are resonating. Someone told me it could be the steel belts separating, possibly caused by the many potholes around here. I think I'm going to buy a new set. Thanks!
