There are two problems with trailer tires. The load range is usually too low, and the speed rating is also too low. I refuse to buy tires in load range C or 65 mph speed rating. If we all would do that, they'd stop making junk tires. I went from the 205/75R14s to Taskmaster 215/75R14s from etrailer that are LRD and rated for 81 mph. Not many miles on them yet, but so far, I'm very happy. They were about 1/2" taller than my old tires, but that doesn't seem to be a problem. I filled mine to 65 psi and it rode fine. I put the same tires on my boat trailer. The problem with blowouts is the damage they do to both the trailer, and potentially the other tire. I've replaced the fendere on my boat twice now. That costs more than the tire. I got a little damage from the two blowouts on my ROO.
