I was conerned about tires too but... I think if the balance was off they would vibrate - they don't at all. As far as slipped belt - how to tell. I mail ordered from Tire Rack and had a tech at Porsche Audi dealer install after hours. Anything's possible. Anybody else have an issue like this? If so what kind of tires. Anybody fix problem with new suspension components or new tires?
Thanks,
Brad
