The correct tire inflation pressure is paramount to a tire’s usable life, safety and performance. Follow the trailer manufacturer’s inflation pressure recommendations if available. Otherwise, the inflation pressure for all tires should be adjusted to the one carrying the heaviest load. Please use this link to determine the proper inflation pressure for different load conditions. In order to accurately assess your tires’ inflation pressure, please note that inflation pressure should be adjusted and/or checked when the tire is cold or before driving for the day.
