That's kind of odd. Same size should have the same load rating.
I just looked up some representative tires and the only difference I could find in LT245/75R16 E was the 3042 vs 3086 which I believe is simply the difference between. TRA and ETRTO rating system. I believe they are in the process of harmonizing the two systems and right now you see a slight differential based on the different air pressure charts. It doesn't really mean anything. It's just an artifact.
Not quite. today for a given tire size and Load rating (C,D,E etc.) tires also have a load index giving the exact load carrying capability. You won't find much variation amongst a given load rating and size, but if you look around you will likely see some variation in load capacity. And the variation will correspond to the tire load index.
And it is more common to see a variation in car tires vs. LT tires.
