You can certainly move up to a Load Range G tire, which will have a load capacity of 4,080 pounds at 110 psi in the ST235/80R16 size tire that you currently have mounted. The biggest cause for tire failure is excessive heat. This can be caused by overloading the tires, not inflating them to their maximum psi, or exceeding their speed limit. Trailer tires should always be inflated to their maximum psi as listed on the sidewall.

To replace your tires I highly recommend the Provider St235/80R16 Radial Trailer Tire # PRG80235. This is an excellent 14 ply radial tire that is constructed with double steel belts and double polyester cords for a long life. It also has quite a high speed rating for a trailer tire of 81 mph. It comes with a 2-year limited warranty as well.

I have attached a short video demonstration on this tire that you can check out, along with an FAQ on trailer tires that you might also find helpful.

If you were to upgrade to the Load Range G Provider ST235/80R16 # PRG80235 you will need to inflate them to the 110 psi listed. This is because trailer tires should always be inflated to their max psi so that they can provide the intended load capacity. Inflating them below their maximum psi will essentially reduce the capacity to an unknown number, which may in turn cause you to inadvertently overload the tires with the weight of your trailer. The psi information on your trailer is likely just referring to the Load Range E tires that it came equipped with, which do have a maximum load of 3,520 pounds at 80 psi. When switching to the higher load tires you will go with the new max psi listed on the tires themselves.
