My Z is on crutches!
So, got four brand new Continental ExtremeContact DW yesterday. Discount Tire ordered and installed them! On my way to work this morning, front-right tire just explodes. I was probably going about 65-70mph. Scary as ****! Luckily, there were no vehicles next to me. They are supposedly "investigating" the cause. Road was clean so it couldn't have been any foreign object. Wheel is ok!
