Okay after a visit to the dealer all the BC's he had with the 7k axles had Sailun load range G tires on them. Now of course I have never heard of this brand and will have to start some research on them. I meant to ask the salesman if we could order it with the GY 614 tires and walked right out and forgot. I just don't understand why manufactures continue to put junk tires on high dollar trailers. Our current trailer came with Mission load range E and two went bad before we had 5k miles on the trailer. I checked them each time before we moved the trailer and kept them at 80 psi.
