After about 3000 miles on the new Chinese made radials (Panera, or something like that)that came on my 2012 Ever-Lite, I had two blow-outs. Both were properly maintained with a TSP temperature and pressure monitoring system. Always proper pressure, never a heat issue. I replaced them with Goodyear HMG 2020's bias ply,made in Canada. It says on the sidewall they are made exclusively for U-Haul. It was the best tire decision I have ever made. They are tough, tough tires and the trailer handles sooooo much better on the interstate. Would never buy anything else for my TT.
