Tire Pressure Calculator
Calculate optimal tire pressure based on your weight and riding style
Your Information
Recommended Pressure
Recommended Pressure
24.3 psi
1.68 bar
Safe Range
20.7 - 27.9 psi
Note
Start at recommended and adjust based on feel and conditions
Pressure Tips
Check tire pressure before each ride. Higher for speed, lower for comfort
Quick Facts
1-2 psi increase for every 10°C temperature drop
Note
Tire sidewalls show max pressure. Actual optimal is often 10-20% lower
How Tire Pressure Calculator Works
This calculator estimates optimal tire pressure based on total system weight and tire dimensions.
- Total weight = rider + bike weight
- Tire size affects pressure distribution
- Road bikes: higher pressure for less rolling resistance
- Gravel/MTB: lower pressure for better traction and comfort
- Pressure affects rolling resistance, comfort, and grip

Tire Pressure FAQ
Does temperature affect tire pressure?
Yes. Pressure increases in warm weather, decreases in cold. About 1 psi per 10°C change.
Should I inflate to the sidewall maximum?
No. The sidewall shows the maximum safe pressure, not optimal. Use recommended pressure for your weight/style.
What's the difference between psi and bar?
1 bar = 14.5 psi. Bar is metric; psi is imperial. Most pumps show both.
