What causes this?
Was driving back home from a show and after about 10 miles I started feeling that the car was shaking/wobbling. so I slowed down and it went away (60-> 45) but everytime I speed up I felt the vibration again so after a mile or so I decided to check it out, so as I slowed down about 30mph or so I heard all the air come out of the tire, like a airbag or a baloon deflating, and I knew I had a flat.
Im just wondering what would cause this? It is not rubbing the inner wall since the inner wall of the tire does not have regular wear on it, just a certain 6" section witch looks like the tire melted. if you look at one of the picks the 345 is not rubbed off but everything below it is, so it was not a long tirm thing. Im just curious b/c I dont want it to happen to my other tires.

How much PSI do you run in them?
How old and how much mileage?

on 20x14 rim
30-35psi
milage 5k
put them on end of January this year
You've got tires 4 inches wider than stock? Gee I can't see why you'd have problems.
edit: And the rims are wider than your tires?

Here's my guess....
Looking up 345/25/20 tires, I found two matches:
Pirelli Pzero which lists recommended wheel size of 11-13½", optimal 11½".
Nitto Invo which lists recommended wheel size of 12-13", optimal 12½".
Your larger wheel (14") means that the tire is stretched to fit on the wheel. The sidewalls are not in the optimal configuration (perpendicular to the wheel) so there is more flex in them than expected. Sidewall flex causes them to overheat and eventually fail. It's just like running a tire at too low of a pressure.
Another thing to keep in mind is that because of the negative camber, most of the load on the tire is on the inside edge, I'd bet the outer edge of the tire is hardly ever touching the ground.

my camber is still good, and if you look i dont have much wear on my inner tire, the wear on the whole surface is even but i guess most of the weit is on the inner and when drifting and burning out i have worn it down?
