RV Trailer Tire Pressure


Tire inflation is the most important aspect of tire maintenance. RV trailer tires lose about 2 PSI every month, causing under-inflation. Check the pressure of each tire at least once a month to ensure your tires stay in top condition. Check the pressure before you embark on your trip and every day during your trip.

Problems Caused with Incorrect Tire Pressure

RV trailer tires with the incorrect pressure configuration will consume more fuel. With fuel prices the way they are these days, this is essential. Correct tire pressure can lead to an increase of a mile per gallon.

Under-inflation is a major problem for RV trailer tires. Under-inflation causes the tires to increase in temperature, leading to an expansion of the tire walls. What results is a tire blowout.

Overloaded tires are the number one problem when it comes to RV tires. It is a serious issue that can cause damage to your RV trailer tires. Weigh your axles on platform scales to ensure your tires are not overloaded and check for correct weight distribution.

Checking RV Trailer Tire Pressure

  • The recommended tire inflation pressure can be found in your owner’s manual and on the wall of the tire itself. It will depend on the tire size and the load of the RV.
  • It is best to check the pressure of the tires BEFORE you drive to ensure an accurate measurement, also known as a COLD reading. This is due to the tires increasing in pressure when heated by being driven which is a misleading figure. Tires must be configured against their COLD readings.
  • To check the air pressure, remove the cap on the tire and check with a tire pressure gauge. This is where you should invest in a quality tire pressure gauge. Consult your owner’s manual for the correct PSI required. Check the inside tire for dual fitment RVs as well.
  • Go ahead and drive to the nearest service station to inflate your tires to the correct pressure. REMEMBER that you are adding pressure to the COLD reading. Inflate the tires until your tires match the recommended pressure set by the manufacturer.
  • Make sure the cap and the valve is not dirty or wet. Clean the cap and the valve if they are.
