I think you should have done a few more burnouts..

haha, ive never seen them do that either. We have some tires that are over 25years old on some farm equipment,, and they still hold air, and not dry rotted.

What brand are these tires you have?

I'm going to say it is a combination of heat cycles from driving in the hot weather of Arizona and being Michelins. I noticed alot of Michelins "dry rotted" when I used to change tires. Although, I never heard a lot of complaints about the brand. If the tires are giving you the traction and miliage you expect I wouldnt worry about it too much.

It has to do with the age and the type of tire shine that is applied to the tires. When tires tend to sit on concrete (which happens always) it causes them to dry rot.
Just think about this, when you store a car, boat trailer, or any trailer on concrete, it is recommended to jack the tires off the ground and block the axles so the tires are not touching the concrete or floor. The condensation that is created under the tires promotes the rubber compound to break down.
I see this a lot since I work at a repair facility on the weekends. It really doen't hurt to drive on them. It doesn't mean the tire is finished. Just the outer ply layer of the tire has surface cracks. They will still be ok.
Don't give up on the Michelins just yet. They are still one of the highest quality tires on the market. The Goodyears come in second.
I like the new Yokohama Goelander HT/S directional performance truck tires.
I can't give a review on them just yet, as they are little too new in the market. The people that do own them seem to like them.
I've read here on this site that they last a decent amount of time and hook very well.
How much tread is left on your tires anyways?

If you actually drive that truck every now and then you might not have this problem!
