A trailer tire should ALWAYS be inflated to its maximum rated psi pressure rating as shown on the tire's sidewall. At no time should you over- or under-inflate a trailer tire even if it is operated well below its rated weight capacity. There is no benefit from altering the inflation from the specified pressure and doing this can cause tire overheating and premature failure. You may care to check out the linked article on trailer tires.

If your trailer tires show evidence of cupping (wear in an isolated spot) this is usually due to the tire being severely out of balance.
