The interesting thing about trailer tires is that they need to be inflated to their max psi rating at all times regardless of load. This ensures that heat does not build up which causes premature failure. So for a tire like the Loadstar 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30670 that has a 90 psi max pressure rating you need to make sure you inflate it to 90 psi when cold at all times and you'll be set.
