Everybody said the Endurance tires were the best. So I took off my 8 year old Carlisle HD tires and replaced with brand new Endurance tires. The Endurance tires lasted about 500 miles and blew out. I had the trailer professionally aligned and they seemed perfect. Called Dobbs Tire who installed them and they said there is NO WARRANTY on my 26 day old tires. I have tire pressure monitors and they were at 64psi when they blew.
