First, try checking the tire's side wall, the recommended psi should be listed.

For our trailer tires with a 4.80/4.00-8 size, a 3-3/4 inch rim, load range B, the maximum load is 590 pounds at 60psi.

Each tire manufacturer could have different recommended psi for their tires, so it is important to find information for your tire's manufacturer.

It is important to remember to inflate your tires when they are cold, and to inflate them to their max psi.
