If the tire size on your tire starts with the letters ST then you will want to keep your tire pressure at the max psi stated on the tire sidewall-even when it is cold. If you can tell me the tire size and load range, I would be happy to give you the typical max PSI and weight capacity for that setup.

ST stands for special trailer tire and is used mainly for trailers. It is best to keep trailer tires inflated to the maximum pressure because that ensures that they will perform at their stated weight capacity. This will also help prevent wear and tear on the tires and will also help to reduce the amount of heat build-up due to their thick sidewalls. You always want to keep trailer tires filled to their max. I will attach a help article that will go into further detail for you.
