RV Tires
A tire that is under inflated will build up heat that may goThe most important factor in getting the most life of you tires is maintaining proper inflation above the limits of the rubber and radial cords. An under inflated tire will cause poor handling of the RV and irregular tire wear and also decrease your mileage.
Over inflation will reduce the contact with the road, thus reducing traction, braking capacity, and handling of the vehicle. Over inflated tires will give a harsher ride and uneven tire wear.
Federal Law requires that the tires maximum load rating be molded into the sidewall of the tire. The amount of air pressure you need to use is dependent on the weight of your fully loaded RV. It is important to note that the cold inflation pressure for the tire must never exceed the maximum inflation rating stamped on the wheel.
You should check the air pressure every 2 weeks or at least monthly and before any major trip. Check tires when they are cold and have not been driven on for more than a mile. Use a quality truck tire air gauge which has an angled head. Make sure you use valve stem caps to reduce the change of leakage through the valve stems. Valve stem extensions are recommended but be sure they are quality stainless steel braid reinforced and are securely anchored to the outer wheel.
With proper care you tires should last 5 to 7 years.
