***nitto Nightmare***
In all likelyhood, this is your first blowout...or VERY quickly deflating flat. Your sidewall didnt just seperate from the tire. What happens on a blowout (most likely road debris) is the tire goes from 32 psi to 0 in about a second or two. The rim lip or bead is now trying to touch the ground and it has all of a 1/3" of rubber keeping it from doing so. At any decent speed (ill assume 40+) its only going to take a bit over 5 seconds or so to completely eat through that rubber and thus completely cut off the sidewall. It happens quite often. It happens to all manufacturers. Its the unfortunate side effect of a blowout. To better illustrate what may have happened. Have any of you had a slow leak, or ran your tire VERY low on air? Like 5psi low. Well, when the tire is taken off for repair/inspection youll see a groove on the shoulder of the tire (inside), and a bunch of rubber dust & fragments. Thats the beginning of the wheel cutting the tire.
Good luck
i think im gonna have to go w/ 18" BFG's now. I rather have tires that slide a lil in the rain ---- than ones that crack for no reason.
If Todd is right, which I suspect he is, you will probably find a hole somewhere in the tread or sidewall which would be your smoking gun.

Drag radials are not your common everyday tire. First off...most of you run these tires at a lower pressure than you would your normal every day tires. Me personally...my nittos were always around 20-22 for max street grip. That alone is putting additional pressure on the sidewall of the tire. Less air to stabalize the weight of the car. More flex in the sidewall during cornering, and even when the car is at rest. Also, the drags are a softer sidewall without reinforcement. Again, making it more prone to cracking. Ive seen what you guys are talking about. Ive seen it on other tires as well. This isnt a dry rot condition. Its more cosmetic than anything. Dont get me wrong...I understand that you are like me and have the occasional high speed romp, and are a rather spirited driver, but its not a major concern. Another contributing factor with these cracks is lack of use. Some of you dont use this as your daily driver. These tires dont like to sit still for too long. Low pressure, soft sidewalls, little use, means a lot of pressure on the sidewalls. If you treat these tires like a regular street tire...I doubt you'd see these cracks. Just .02 from the tire guru

Not saying your wrong or anything but if the sidewall of a tire is softer how would it be more apt to crack as opposed to flex or give.For example glass and diamonds are very hard matireals and will crack very easy and if put under any real movement would crack.I know tires and glass are not the same but the basic physics is,or at least I would think it would be.I could see were the nitto might have flexed to much over a period of time and possibly tore causing the blow out.just a thought I could be wrong.
Nitto is owned by Toyo Tires, which is a major name brand manufacturer. I'm going to look into the Toyo name brand versions if the Mickey's don't come out soon enough.

after being in the tire biz for a while, I saw tons of this type of issue. It's just the luck of the draw. Sure, every once in a while, a tire does find it's way to market with actual defects. But most "defects" cause a separation condition, in which the tread area begings to separate from the carcas of the tire.
It's funny to see some people take everything they read on the net to heart
