what are trailer rated tires
A trailer tireâs load rating refers to how much load the tire is designed to carry at its industry specified pressure. Trailer tires should always be inflated to the maximum psi rating as indicated on the tire. If under inflated, a trailer tireâs side wall will build up more heat faster and cause the tire to fail. This is why trailer tires are designed to have thicker sidewalls â so that they can handle more vertical load.
