Tire Pressure Calculator
Find the recommended tire pressure for different temperatures and load conditions. Always use the vehicle manufacturer's recommended cold pressure as your baseline.
Tire Pressure Tips
- Check pressure monthly and before long trips
- Always check when tires are cold (driven <1 mile)
- Use the vehicle door placard pressure, not the tire sidewall maximum
- Inflate to the higher end of the range when carrying heavy loads
Frequently Asked Questions
Should I check tire pressure when tires are hot or cold?
Always check tire pressure when tires are cold (driven less than 1 mile). Hot tires can read 4–6 PSI higher than cold pressure.
How much does temperature affect tire pressure?
Tire pressure changes approximately 1 PSI for every 10°F change in temperature. Cold weather reduces pressure; hot weather increases it.
