Tire Load Range

G and H share similar loads depending on ply. You need to know how many ply in the H and the G to determine if the rating is appropriate. There are a few other Load Ranges that share similar crossovers due to construction. I don't know why tires in that group carry different load ranges when their actual carry capacity is the same; but they do. I guess it's similar to the load "index" issue with LT tires that are both 120 and 115 depending on mounting characteristics.

I don't need to know the plys at all, I just have to look on the max load on the side of the tire and it says 6,175 lbs and the correct tires on the back of the same brand and model in H say 7,160 lbs. It's really pretty simple.

Not sure I understand... and are you saying that you just always inflate to max, without any regard to what the rig actually weighs?
I always look up my particular tire on the inflation chart and then add 10 - 15psi for all the variances, before leaving on any trip.
