I've had the car 3 months and put 7500 of those miles on it (it's an '05).. let's just say I was taking advantage of slick roads when it finally gave.

Funnily enough, the tread separated but it kept pressure long enough to drive it up a wrecker .. and still had pressure the next morning

I wasn't anticipating the expense until the month after next so I just threw the cheap Hankooks on it.. the road noise is incredibly diminished now.. love it.
