Question: what is the difference between 10 ply and 14 ply tires?
Answer: A tire in the same size but with a higher ply rating would be able to combat some of that but can eventually have the same issues. So when inflating trailer tires be sure to go to the max psi. With that said the 14 ply tires will definitely hold up better than the 10 ply. ... It is rated for 4,080 pounds at 110 psi.
