What the hell Nitto?
To the OP, if you can get a better pic of the DOT code on the side of the tire I can tell you when it was made. Same goes for your other 3. I can tell you when they were made and if they are from the same batch.
The hole in this pic looks like a possible puncture source.:
That pic also shows the "Made in Japan" text.
Sucks no matter why it happened. Sorry for the loss. Tires ain't cheap, especially DRs. Good luck with the replacement.
Now that I am home I can see the pics on a computer screen lol. Yes it does look like something punctured the sidewall in that picture. A road hazard warranty, if one was purchased, should cover something like that. A manufacturer warranty wont cover something like that.
I do see the Made in Japan text too. Like I said MOST Nittos are made here.
I've had many "blowouts" in my years of driving crazy **** and this was not like any other one I've ever had. There was no pop or any noises/pulling leading up to it. I was just cruising and then hear the thumping of the tread and a sharp pull to the left and whole lot of white smoke.
I took the tire to discount yesterday before I had to go into work. The guy I actually bought the tires from (who is awesome by the way) said he wanted to look at the tire and find out what happened since he has nt05s on his Mustang. He found a tiny puncture dead center in the tread between the two water channels. We pulled the tire back to look inside and sure enough the whole was about 10x as big on the inside of the tire as it was on the outside. It looks like I ran over something on my commute and it deflated. I'm guessing I didn't notice a pull because the sidewalls on these are so stiff. He ordered me another 315 that will be here Monday.
That's great news, i'm not nearly as afraid to take these to the track any more.

Should make sure its not a manufacturer defect before you bash the tire company alot of people on here dont know their *** from a hole in the ground and will completely write a company off because something like this is blamed on nitto.
