any bad experiances with bridgestone tires?

[BurnoutNova]

the other day, i was on the highway going about 70mph with my k10, and the tread from my tire completely seperated from the tire... like the way a retread does on a semi tire. it was the most insane thing thats ever happened to me while driving.

it felt like i hit 30 feet of speed bumps going 70... and then it was smooth again, and as the tread seperated it ruined the box, tailight, brand new sport bumper i put on, and scared the sh*t out of me. the wierdest thing is the tire still held air.. and i probobly could have driven it home... but i called the towtruck anyway.

it was a 32x11.50x15 bridgestone dueller a/t like new tread and the tire looked new, but it was 4 years old... lucky it didnt ruin my new m/t classic II's

this ever happened to anyone?

i'll get pics as soon as i get home (left for vacation the day after this happened)
