Check tire pressure and tread before every trip.
To check your RV tire pressure, first ensure the tires are cold—ideally after the RV has been stationary for at least three hours or driven less than a mile. Locate the recommended PSI for your RV in the owner’s manual or on the tire information placard, usually found inside the driver’s side door. Remove the valve cap from the tire and press a reliable tire pressure gauge firmly onto the valve stem to get an accurate reading. Compare the reading to the recommended PSI; if it’s too low, use an air compressor to add air until it matches the recommended level, and if it’s too high, release air by pressing down on the valve stem until the correct pressure is achieved. It is recommended to check all tires, including the spare, and to do so before every trip and when weather changes.
Check tire pressure when tires are cold for the most accurate measurement.
Use a high-quality digital or analog tire pressure gauge for precision.
The recommended PSI can be found in the owner’s manual, on the driver’s side door jamb sticker, or on the tire sidewall, though the door jamb sticker is often the most reliable source.
If the pressure is too low, use an air compressor to inflate the tire to the correct PSI; if too high, release air by pressing the valve stem.
For continuous monitoring, consider installing a Tire Pressure Monitoring System (TPMS), which provides real-time alerts if pressure drops below safe levels.
If pressure drops consistently, inspect for leaks using a soap and water solution to look for bubbles around the valve stem or bead.
