Everyone has an opinion on this and all are valid, for them that have'em. For me, my last "5th" came with Carlisle's and though I was diligent in keeping them covered and maintaining pressure, I got VERY poor service from them. Was able to replace two of them under warranty from trailer manufacturer and they replaced them with another make as the manufacturer no longer used Carlisle tires as OE. Gives you an idea of how bad the service life, overall, must have been. Will never purchase Carlisle tires or a trailer so equipped.
Just my 2-cents based on my experience. Good luck and Happy Camping!
