After making a stop in Va. on the way home from Nashville, we pulled out of the campground and drove about 120 miles and stoped for a break. Before we pulled out from our break I checked all of the tire pressures via TPM all were ok. About 5 miles down the road left front tire on trailer blew, found that the tread had come off of the tire and there was some damage to the side of the trailer. So we will be off the road until we can get all of the Towmax/Powerking tires replaced with new tires and the trailer repaired. The trailer next to us in Nashville had the same thing happen to them on the way to Nashville and he told me it was the 2nd time and they were Goodyear 614. Has anyone else had problems with there 614's
