Under inflated tires run a close second to overloading as one of the leading causes of tire failure. The load rating for a tire is only accurate if the tire is properly inflated. Under inflated tires cause extreme heat build up that leads to tire failure. The appearance of the tire looks normal but the internal damage is not visible and can fail at any time without warning.

Tires can lose up to two pounds of air pressure per month. If you don’t check your tires for three or four months they could be seriously under inflated. Ideally you should check tire inflation, and adjust it if required, everyday that you move or drive your RV. If you can’t get into the habit of doing it on a daily basis you need to make it a point to check all tires weekly at a minimum when you’re traveling.

You always want to check the tires when they are cold, meaning that you don’t drive or move the RV before checking inflation. Invest in an accurate inflation pressure gauge. Check all tires and adjust pressure according to the manufacturers recommendation. Do no exceed the maximum pressure ratings found on the tires sidewall. Never check inflation pressure when the tires are hot, you will get a higher-pressure reading and if you let some air out they will be under inflated when they are cold.
