Tire Air Pressure
You should inspect and test the air pressure in the tires of your RV at least once a week, or daily during travel. The maximum pounds per square inch (PSI) are listed on each tire. If air pressure is not maintained, blowouts can occur, especially over the summer months. Check the air pressure when the tires are cold, preferably in the morning. The air pressure rises when the tires are moving on the roadway. A tire is considered cold after three hours of not moving.
Most tires made after 2017 contain nitrogen, and it is indicated by a green stem cap.
If you have questions about how much air to put in your unit’s tires, contact your dealer or the tire manufacturer.
