Maintain pressure at the maximum PSI recommended on the tire’s sidewall for cool running, load-carrying ability and lowest rolling resistance.
Keep a cap on the valve stem to prevent contamination of its internal rubber valve.
Always carry a spare and check its pressure along with your trailer's other tires.
Don't overload trailer tires. Maximum load is listed on the sidewall. Single axle tires can handle 100 percent of their rated load. Dual axle tires must have their loads reduced by 12 percent below the rated amount.
Visually inspect your tires before each trip. Check the pressure before you use your trailer. On long trips you should check your tires’ pressure every morning when the tires are cold.
For long-term storage: cover your tires for UV protection or keep them in a cool, dry place.
Replace every three to five years, regardless of tread wear.
