RV Tire Pressure by Temperature Calculator
Temperature affects tire pressure. Calculate the correct PSI adjustment for changing weather conditions.
Pressure Adjustment Calculator
Pressure you set when tires were cold.
Recommended Cold Pressure
Find this on your tire sidewall or RV door sticker.
Temperature Effect
Temperature and Tire Pressure
Tire pressure changes with temperature. For every 10°F change in ambient temperature, tire pressure changes by approximately 1 PSI. This is normal physics—air expands when hot and contracts when cold.
When to Check Tire Pressure
- Always check cold: Before driving or at least 3 hours after parking.
- Seasonal changes: When temperature shifts significantly (spring/fall).
- Before long trips: Check pressure the morning you depart.
- Load changes: Adjust pressure when you add/remove significant weight.
Proper RV Tire Pressure
RV tires require higher pressure than car tires (typically 65-110 PSI). Find your specific tire's recommended pressure on:
- Tire sidewall (shows MAX pressure)
- RV manufacturer door sticker (shows recommended for your weight)
- Tire manufacturer load charts (calculates exact PSI for your RV's weight)
Underinflation vs Overinflation
- Underinflated: Causes overheating, premature wear, blowouts. More dangerous.
- Overinflated: Reduces traction, harsher ride, uneven wear. Less dangerous but still problematic.
TPMS Systems
Tire Pressure Monitoring Systems (TPMS) alert you to pressure changes in real-time. Aftermarket systems for RVs track all tires (including duals) and often include temperature monitoring. Highly recommended for safety.
