Look at maxxis trailer tires rated one of the best, we found out the hard way and this is what we learned-LOOK AT THE DATE CODE ON THE TIRE-you might have a new trailer but 5 yr old tires, Michelin, goodyear tires weather check REAL bad-they dry out faster-keep the tires at the recommended COLD pressure and keep them there, buy the highest load rating you can afford, thats why we went maxxis, $150 a tire delivered to my door from discount tire.-steve
