I had a 2003 Cardinal 5th wheel with Kenda tires. In 2007 the rear off door side tire exploded and did almost $3000 damage to the trailer on a trip to Disney World. Put on the full size spare, replaced the tire and continued to Disney. On the way back, the front tire on the same side let loose, and I was glad that I had purchased a new tire for the spare. After getting home, I noticed that the two door side tires had baseball sized bulges on them. The build dates showed the tires were built in late 2002. The original spare was cracked in the center of the tread. I called Kenda, the reply was no help. 5 year old tires should not have gone bad like that. They got replaced with Uniroyals.
