Goodyear Endurance tires seem to be going well so far and I have not seen any bad reports such as blowouts with them. I now have Sailun which replaced the Goodyear G614's that replaced the Blowmax after my first trip. Some have used LT tires, but you have to check with the load rating of the tires to make sure the the tires are rated for the weight that the trailer will put oh them. I do have a friend with SOB fifth wheel that put Firestone LT tires on it. He has had them on for six years with no problems. They are 15 inch though.
