Two things should be checked each time you inspect the RV tires - air pressure and wear. Examine the tires daily when you are out on the road and monthly when the unit is in storage.

Determine the correct tire air inflation pressure by weighing the RV fully loaded with cargo, fresh water, LP-gas, passengers and any pets that may normally ride along. Distribute the weight evenly from side to side. Avoid overloading the vehicle and putting undue stress on the tires.

Large truck stops or farm supply warehouses commonly provide scales appropriately designed to weigh the RV. Weight calculations must be determined for the front and rear axles, as well as a four-corner weigh of each wheel. The slide rooms should be in during weighing. Once you establish the necessary weights, refer to the inflation pressure chart published inside your vehicle owner's manual, or available through the tire manufacturer.

Monitor air pressures using a tire gauge. Check air pressures when the tires are cold. Occasionally have the gauge calibrated by a service technician to assure accuracy. Keep in mind that when extras are installed on the RV, such as additional batteries or a satellite, or if cargo weight is increased, the vehicle should be once again be weighed to calculate updated air pressures.

Refrain from customizing tire air pressures in an attempt to gain better traction or promote a smoother ride. Studies have proven that adjusting air pressures as little as 2 psi outside the recommended parameters can greatly accelerate tire wear and cause unexpected blow outs.

Visually inspect the tires each morning. Use a long stick to thump the tires and listen for sounds that may indicate a tire is low on air. Remember to inspect the inside duals. Examine the tire tread for uneven wear or debris that may have become lodged in the tread or between the duals. Take an inventory of the valve stem caps to assure they are all in place.

Pay attention while driving. If the vehicle shakes or wanders from side to side, this could be indication of a bad tire. Have tire repairs performed by a qualified technician.

Proper methods of storage will help you to extend the life of the RV tires. Before you park the vehicle for an extended period wash the tires clean of all dirt and grime using a soft brush and mild soap. Cover tires stored outdoors to protect against the weather. Store the tires with full air pressure and on a flat, solid surface. Replace RV tires every five years.

Remember the tow car tires, which should be checked for air pressure and condition every drive day. You may not detect a flat tow car tire while driving the RV down the road. Have the tow car tires rotated each year and fully replaced every five years.
