There are a few "heavier duty than the normal" available. The issue, I believe, is not the tire rating, but the issue is finding 15" five lug wheels that will support that much weight. Looking at the "realistic capacity", the trailer GVW is 3960 pounds, (shipping weight 3305 + cargo capacity 655 is 3960 total) Keystone built it with tires rated at 2150 each (single axle trailer) for a total of 4300 pound tire rating. That's "before the new RVIA tire requirements" and is barely over the actual trailer GVWR.
If the current axle hubs are built for 5 lug wheels, it's going to be difficult to find wheels that will support the 2830 pound/80 PSI rating of the LRE tires. It'll be even more difficult to find wheels to support the LRF "all steel 15" tire rating.
It's not that 15" tires with a greater capacity, it's finding wheel that fit the 5 lug axle hubs. If it had 6 lug axle hubs, there are a couple of wheels available and upsizing to 16" wheels is a possibility (provided the wheelwell clearance is adequate)...
Bottom line, at least for me, is finding 5 lug wheels that will support tires rated higher than 2150 pounds, which is the current 205 75R15 LRD tires.
