Steps to Maximize Your RV’s Tire Life

For many RVs, tires can be the weak link that disrupts travel if not properly maintained

By Tire Expert and FMCA Member Roger Marble 

For many RVs, tires can be the weak link that disrupts travel if not properly maintained. Quite often, overloading is the cause of tire failure.

Follow these simple steps provided by tire expert and FMCA member Roger Marble to increase your chances of problem-free travel. 

Initial Steps

Once you take these two initial steps, you’ll only need a few minutes each month to maintain your properly inflated tires.

1. Know the proper tire inflation pressure for your RV.

2. Ensure that your tires are always inflated to that level.

But how do you find out what your proper inflation number should be?

Determining the Correct Tire Inflation Pressure

First, it’s important to note that the proper inflation level is unique to your RV.  Following the suggested inflation levels provided by the manufacturer on the tire certification label is only the beginning. The manufacturer’s suggested tire inflation pressure is based on an assumption, but only you are able to determine the true weight of your RV during travel.

To learn your RV’s true weight, pack it with all the items you expect to carry on your trip – clothes, fuel, food, water, family members, and pets. Then visit a scale that can weigh your RV and provide weights by individual wheel position. This is important because the required air pressure is based on the load on each individual tire. You also can book an appointment with the Recreation Vehicle Safety and Education Foundation (RVSEF) at most FMCA events to obtain individual wheel weights. 

Once you know the load being carried by each wheel position, you can determine the minimum inflation pressure needed to carry that load.  We recommend visiting https://rvsafety.com/ to help guide you.

In addition, you can find a “helping hand” by visiting the FMCA forums, where you can find threads specifically dedicated to RV tire maintenance.

Determining the Cold Inflation Pressure

You will also want to be sure to determine your tires’ minimum cold inflation pressure (CIP).  Visit tire manufacturer websites to find your tire brand and a table that has your tire size. Once you find that, look for the inflation level that carries your load or greater. This is the minimum cold inflation pressure, and it is recommended you go up in inflation by about 10%. Changes in air temperature, for example, can cause minor fluctuations in tire pressure, and increasing the CIP will help to eliminate the need to adjust tire pressure each time these fluctuations occur.

Measuring Tire Pressure

When measuring your RV’s tire pressure, try to make sure the tire is cool and in the shade. Ideally, the tires will have not been driven on or exposed to sunlight for at least 2 to 3 hours.  That usually means the best time to check your tire pressure is first thing in the morning or late in the evening once you’ve settled in after a day of travel.

Getting started is always the hardest, but by making tire maintenance — and measuring the PSI of your tires — part of your travel routine, you can greatly reduce the risk of experiencing tire failure while on the road.
