Many RV owners inflate their tires based solely on the pressure listed on the sidewall. But that number represents the maximum pressure for the tire’s maximum rated load-not necessarily the correct pressure for your specific RV.
Proper tire pressure depends on how much weight your RV is actually carrying. The safest approach is to:
• Weigh your RV when fully loaded for travel
• Use your tire manufacturer’s load and inflation charts
• Set pressure according to the heaviest wheel position on each axle
• Check pressure regularly with a reliable gauge
Underinflation can cause excessive heat buildup and premature failure. Overinflation relative to load can affect ride quality and wear patterns.
Tire pressure isn’t guesswork-it’s math based on weight. Taking the time to set it correctly helps protect your tires, suspension, and safety on the road.
