I wonder why the shorter sidewall would be rated less than a 16"? My LT265x75R16's are good for 3415 lbs. Is it the 70 series v/s the 75's?

All tires of equal size are rated the same in the same load rating. More air volume = more load capacity in the same load rating. Someone can correct me if I did not explain correctly.
You could try 19. 5s. Gets a bit spendy, though.
