10% over axle rating doesn't take into account the pin weight on a 5th wheel, which on my trailer is 3,500 pounds (scaled). My trailer has 3x7,000 pound axles and increasing 21,000 by 10% comes to 23,100 pounds to satisfy RVIA.

However, subtracting the pin weight, my three axles only need to carry 19,600 pounds. 19,600 equates to 3,266 pounds per tire - well within the load range of any E rated tire. BTW my GVWR is 19,000.

The way I read it, the tires have to have enough rating to handle 110% of the axle rating, nothing to do with pin weight . I have two 7K axles ,I need tires that according to RVIA need to have a rating of 7700 lbs, 3850 lbs per tire. My GVWR is 15,500 minus my pin weight of lets say 25% is 3875, so thats 11,625 on the axles or in the ideal world 2906 per tire, so in reality I need a tire that has a rating of lets say 110% of 3000 lbs or 3300 per tire . But it does not work that way .

No idea what tires you are running, but if that fifth wheel was new, pretty sure the RVIA sticker would be saying 7700 lbs, not the 7000 like previously. So your tire rating would also have to be 3850. So even back before the change ,in reality coming out of the factory your OE tires needed to be 100% of axle rating or 3500 per tire . Does not matter what pin weight is .

I am running a G rated tire on 7K axles, and I am overkill, as many do, and will continue that way.
