We purchased our BH 3055RL new in 2010 with the original TowMax tires. Knowing that we had till 2015, based on the DOT, to replace, we were going to replace them this Fall. We visually check our tires and pressure before each trip and have a TPMS system. On July 2 of this year, on our way out of town for a camping trip, one of the tires blew and did $3k worth of damage. It's still in the shop waiting on parts from Heartland. When the tire blew, we had the spare put on and went straight to a local tire shop to replace them. They said all were bad and replaced them with TowMax tires. When I questioned the brand, they said they are good tires. We took our fifth wheel next to the dealership for repair and they too said TowMax are good tires. These are E rated ST tires. We actually did well on our first set, but are you saying that we should change the new ones out too? This dealership has always been good on recommendations and tire quality and if I talk to them I bet we can get at least a credit. The rig has been sitting on these new tires since July 2.
