Regardless of the brand of tire, going to Load Range D is good advice. I went up one load range on our 5vr and it made a load of difference. Because you can put more air pressure in the higher range tire, they run a lot cooler. It was the heat that the tire produces that caused them to fail in our case. When I had LR D's on the trailer and the pressurized to the maximum of the tire, they always ran hot. They were always hot to the touch. I bought temperature gun and measured temperatures on the LR D's on hot days of30 to 40 degrees about ambient.We just completed a 7000 mile trip to the Southwest US andunder the same conditions, the LRE's on the trailer run about 10 degrees above ambient.
