5H MAX LOAD 2150
6H MAX LOAD 2830
Some 15" wheels are rated for LRC (6 ply rating) tires, some 15" wheels are rated for LRD (8 ply rating) tires, some 15" wheels are rated for LRE (10 ply rating) tires and some are, depending on the number of lug holes, rated for different tire ratings. It's sort of like playing a trumpet, press 1 or 2 or 3 or none of the valves and get something different out the end.... Wheels are much the same, depending on the manufacturer, style, lugs, casting and even the aluminum alloy used in the casting.
There are a number of "competing wheel brands" many that look "identical on the road side" that are rated differently, some 15" 6 lug wheels may only be rated for 2150 pounds while some 15" 5 lug wheels may be rated 2540 pounds. It depends on what brand and what rating is cast on YOUR wheels. Making a "best guess" that you "might have" something that looks like mine but is a different manufacturer's wheel... Well, that gets you to the *** U ME factor. I'd urge you to check the back of your wheels and not guess on what "might be".....

Thank you for the good info. I think I have decided to go with the Carlisle Trail HD Trailer Radial, it seems to get mostly good reviews. So I will just need to take the trip up to storage and crawl underneath to see what ratings they have.
