Is that 3000 lbs per tire a estimate or actual scaled weight ?
Rv trailers with slide outs are notorious for weighing several hundred lbs different side to side...plus running in a strong side wind all day long can over load a tire on the down wind side if it doesn't have any reserve capacity. Tire experts say a 15-20 percent reserve capacity is a better idea.

What is the trailers GVWR ?
Does your trailer have 6k or 7k axles ?
Lots of 16" trailer wheels rated for G tires (3750 lb ) at 110 psi. Check your wheels for proper load and pressure rating.

I had the 5th wheel weighed at the FROG event last year. they used a scale on each of the 4 wheels. So the 3000# weight, side to side, is pretty good. The trailer weighs 15000 pounds. Both sides had about the same load.
I have 16 inch wheels, 6 lugs wheels, 6,000 pound axles, trailer GVWR is about 14,000 pounds.
If my wheels could take the extra pressure, I would put on "G" rated tires. However, I like the good record of the Michelin RIBS. It is either the RIBS or G rated tire.

And, how can I check the rating of the 16 inch wheels to see if they can take the higher pressure load??

Get the "G" tires and run them at 85 that will give you 3,170 capacity or at 90 that will give 3,300# per tire. Your rims will be fine!

I did the same with 6 lug steel wheels on my Avion. Went from E's to G's and ran 85 for many thousands of miles snd had perfectly even tread wear.

Good information . . . thanks. The "key" question is . . . . . .how heavy is your 5th wheel? Is it close to 15,000 pounds? I think that I would be okay with E rated tires if my trailer was 1,000 pounds lighter.
So the question is . . . Would the Michelines be better than the G rated tires at 90#s pressure?????
We are full timers, and can't really get rid of extra weight.
Thanks . . . ken
