I've used Deestone before and they are better by far than Carlisle tires. This tire is rated for trailer highway use and replaced a Carlisle tire that had rotted away to useless in only two years time on my seldom used generator trailer.. No more Carlisle for me as every one I've ever bought lasted only a short while before dry cracking and leaking flat. The Deestone tread and sidewalls also appear to be thicker and stiffer for longer life.
