I've never heard of ANYONE recommending Carlisle trailer tires. My current 28' has 16" wheels so my trailer tire selection has been much better than my previous 24 that had 15" tires. No matter what I used on that one (good year, Carlisle, Maxis, Hi Run.... 8 plys, 10plys) I simply had to replace them every two years no matter what they looked like. Life in the desert..... if it aint tires, it's batteries :)
