I didn't get the corporations involved. This was six years ago. The tires had 46,000 (or so) miles on them. I had just changed from a 5th wheel that had a 2400 pound pin weight to one that had 3400 pound pin weight. With the new tires installed, at 65 psi, I found that the tires were very close to touching in the static postion. My surmise is that they would touch when they flexed. Since I went to 80 psi, there is adequate, in my opinion, clearance. I have not had any problems since. I now have 60,000 miles (or so) pulling this trailer.
