Tires
Anybody know what could cause this to happen? This happened to my Right Front tire and my Left Rear tire. My tires are less than 6 months old. Thank God I wasn't going my usual 120mph! I contacted the manufacturer and the retailer too.

for the record, I'm a tire engineer in the U.S. Govt. working directly with NHTSA on a constant basis.....I ran the Federal Tire Qualification Program for 13 years....and have done a ton of tire failure analysis... some of which was used in litigation..... if you have taken proper care of your tires, you need to go to NHTSA's site and fill out a defects report.
That is the classic belt edge separation. Causes: running excessive speeds under inflated (too much heat generation). Racing on road course tracks under inflated or to extreme.....or defect in the tire. I can see you have worn down the tread surface pretty good. that one crown edge where the failure occurred is very worn...
a "zipper" begins and the belt edge unzips...
as stated above, hitting a huge pot hole the right diameter will also cause this separation.. it compresses the casing structure beyond its limits and the weakest point is the edge of the belt package...especially in a non speed rated tire which has no belt edge wedge supports, which high performance tire utilize.
What brand designation was those tires? what psi were you running?

And I wasn't doing 120, I was hitting 140 on the front straight
Fortunately I caught it before it turned into that \/\/\/\/

Now earlier that day I was hitting 150mph going to Effingham. I check my tire pressure everytime I take the car out! My thing is that They are Z rated tires. They should handle that speed with no problem. No pot holes though. On the rear tire I was rolling too but whats the purpose of having these Nitto 555 and they can't take the beating. Any suggestions on another brand tire?
