I think your thinking is correct thinking, I think.:) The manufacturer could have gotten away with ST205/75R14 load range C rated at 1760 each on your axle. At least they gave you the next wheel size up. If the wheel is at least 6" wide and you have the room in the wheel wells and between adjacent tires, you could run the ST225/75R15 load range C for 2150 pounds each. That would give you more than 15% if you find yourself running at the max of 3500 pounds per axle some day.
Doesn't the tongue weight have to be included?
I thought we were just discussing the particular posters axles, what they are rated for, the tires the manufacturer gave him, and what margin he is running them at. The point I was making, regardless of tongue weight (from 5 pounds to 1500 pounds), should he find himself running 3500 pounds on each axle some day, the current tires won't have the 15% margin, however, the ones I suggested would have more than 15%. The tongue/pin weight would just be the amount over 7000 pounds that the posters trailer would weight under those conditions and would have no bearing on the appropriate tire for running at maximum GAWR.
