Another Subj . . . TIRES
All . . . .A very worn out subject. I really need your help in buying a new set of 5th wheel tires. We have a heavy (3000 #s per wheel) Cedar Creek. We bought 5 GY Marathon tires within the last ye...

I would not buy another ST tire, but it looks like you need "G" rated LT tires rather than the "E" rated tires like the Michelin Rib. The "E" rated tire's weight limit is 3042 lbs. If you're at 3000 lbs. per wheel, it won't give you much leeway.
However the "G" rated tires can be inflated to 110 psi, so if you wanted to run at sidewall pressure you would need wheels that will allow you to inflate to 110 psi. I run "G" rated Sailun S637 tires on my 15,000 lb. triple axle toyhauler, and inflate them to 100 psi.

Thanks, but I don't think that the "G" rated tires will fit on a 16 inch wheel. As for tire ratings, the Marathon's are rated for 3400#s, while our 5th wheel weighs 3000# per tire. I think that the Marathon's are under-rated.
I have been using E rated Marathons for 13 years on fivers under 12K GVWR and have never had a problem with any of them.

I keep hearing that but two sets, one U.S. made and one Chinese over 13 years and no failures. Makes me wonder what people do with them.
Mind you, I am running them at 1000 lbs under their load rating.
Very well could be why the success with the Marathons. Most RV.s use the tires max load carrying capacity to determine their weight ratings. So Most RV's with little cargo are at the tires max and they just don't hold up.
