Another potential cause is UV damage to the tire. Even though the front of the tire is protected by the tire cover, the back is open to sunlight and reflected UV rays that bounce off the trailer endcap. We often think our spare tire is "protected" by the cover, but in actuality, there's still a significant part of the tire that's not covered. Years of sitting in this environment on the back of a trailer in the SW desert sun, with little or no protection, is it really any wonder that the tire was weakened significantly before it ever touched the ground under the trailer?
