Proper RV Tire Pressure: Finding the Right PSI

Duration: 2:33

Just because your RV’s tires say they can handle a certain PSI doesn’t mean the listed PSI is the ideal one for your vehicle. Proper tire inflation requires weighing your vehicle with the load you’ll be carrying, and filling to match that number. In this free video lesson, RV maintenance expert Dave Solberg teaches you how to find the correct RV tire pressure for your motorhome, coach, fifth wheel, or whatever else you drive.

We see RV owners make this mistake all the time, and for understandable reasons. Drivers are constantly told that the number on their tire’s sidewall is what you need to look for, but what they’re not often told is that that number is the maximum RV tire pressure at the maximum weight capacity. Unless you’ll be hauling max weight, you don’t need max pressure!

What happens when you fill your tires too much?

Overinflating your tires can lead, of course, to the unexpected and dreaded pop while working your way down the highway. But it can also cause lower fuel efficiency as well as poor braking and handling abilities due to incomplete tread contact with the road. To prevent all of these things, Dave recommends taking your RV to your nearest CAT scale to get an exact measurement, incorporating all weight that you’ll be carrying on your next trip. Just put your RV on the scale and see your precise readout!

Once you have that number, you can refer to your tire manufacturer’s conversion chart to find the ideal RV tire pressure for your model, no matter if you use a single or dual system. It’s that easy! Be sure to do your homework and spend about $10 to get the weight and inflation right, and you’ll enjoy a smoother ride with better fuel efficiency, reduced risk of accidents, and a longer tire lifespan. Ride safe out there!

    Is this the method the same for a travel trailer? I would think it would be, but I just want to make sure. Thanks

      Yes, it is the same procedure when checking all RV’s including travel trailers, 5th wheels and Motorhomes.

      Hello Jack,

      Thank you for your patience while I asked the expert, here is his reply:

      Yes that is the best thing. Not all tires are going to need pressure fluctuations and a chart to follow. All tires are made differently and if yours aren’t indicated on that chart of needing different pressure for different weights then you want to follow the max PSI listed on the sidewall of the tire.

    I assume this would apply to my trucks rear tires as well when pulling a Travel Trailer

      They do not have a tire inflation chart for Kenda tires. When companies don’t have a chart they always just recommend setting to the max PSI to ensure proper inflation.
