I found a screw on the rear driver side, so I brought my Camaro in. They said it's an easy fix, fortunately the screw was impaled sideways, no real damage to my run-flats.
Drove back home on the freeway, whole car was vibrating rapidly, steering wheels and the car frame!
Went to the nearest discount tire near my place at Scottsdale, they said my tires were installed back on at the wrong direction AND it wasn't adjusted/aligned at all.
How..? Tires is what you work on every day, every hour, how can an employee screw it all up. Unbelievable.
What's the point of spending $300 on warranties when this is the type of service I get.
