Maxxis Trailer Tires-why so much better?

I had blow out after blow out with my Carlisle but I found out forest river put two different sized tires on my tt. so I got fed up and bought over kill tires but still Carlisle tires. never had any more problems with tires after that. and I mean no failures at all. I think there are two reasons for tire failure is wrong load range for the tire and people driving too fast for the tire rating. face it, I have seen on this forum of people who don't know there is such a thing as speed rating on a TT tire and they drive down the road doing 70 and 75+ mph. speed rating and weight ratings are totally over looked by some people.
