Ok, as you may have seen in my other, recent thread, I've relocated to DC. Not sure if the crappy streets with pot holes, frost heaves, and other products of road neglect bent my wheels or if it's the tires, but the car has an annoying wobble, humming sound at the wheels. My previous car, a G35 Coupe had the same thing as the tires approached 12k miles. The SRT6 is right around 13k now. Anyone else experience this? I'm hoping it's just a tire issue.
