NC you will be much better off with a QUALITY "E" tire since you have 3 axles. With 20K CVWR the most you will ever see is 2,666# on each tire. I know you like to run full psi on your tires but with then "G" tires at 110# it will beat your RV to death!!!
Maybe not though, that 2,666 lbs. assumes that all tires will bear the same weight, and I think that's pretty rare due to the configuration of 5th wheels. Mine has a spread of nearly 500 lbs. between the 6 tires. So it's conceivable that one, or possibly two, tires could have considerably more weight than the others. That could put it at, or perhaps over, the weight rating of the "E" rated tires. I think I would err on the side of caution, and to give me some room for error. I run the "G" Sailun tires, but do run them at 100 psi and not 110 psi.
I weighed all my wheels with a Shurline scale just for curiosities sake. A couple tires weighed under the average and a couple were over the average.
