A Mopar guy from the Northwest, Washington/Oregon area was about 10 miles from Las Vegas on his way to Mopars at the Strip when he blew a 8 year old tire on his cherry RR vert, It made a huge mess out of the car, amazingly he wasn't killed. It looked like he hit guardrails on both sides of the car The amount of tread is not a good indication of when a old tire will fail.
