I recently had a blowout with my less than a year old GY Endurance. I was taking it out on a short test run for the new fan clutch I put on my truck. Pulling the trailer up a hill was the easiest way I knew to get it hot enough to engage the fan clutch. Since it was such a short run, I neglected to check the tire pressures before going. So, I blamed myself for the blowout. Turns out the pressure in the other tires were fine. It was a road hazard ... something long as it penetrated the tread and scarred the inside of the wheel. I probably drove the better part of a mile before getting off the freeway. The tire was shredded, of course. But surprisingly, the rim and trailer had no damage at all except where the hazard made contact inside the rim. AAA put on my spare, I went straight to Americas Tire and they replaced the tire for free (I had purchased road hazard insurance when I bought the tires). I did have to purchase another coupon for the new tire ($24).
