1. What is an Optimal Tyre Pressure Calculator?

Definition: This calculator estimates the ideal tyre pressure for road bikes based on the combined weight of rider and bike, and the tyre width.

Purpose: It helps cyclists find the perfect balance between comfort, rolling resistance, and puncture protection.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Optimal tyre pressure (psi)
• \( W \) — Combined weight of rider and bike (kg)
• \( W_t \) — Tyre width (mm)

Explanation: The formula accounts for weight distribution and tyre volume to recommend a pressure that balances performance and comfort.

3. Importance of Proper Tyre Pressure

Details: Correct tyre pressure affects rolling resistance, grip, comfort, and puncture protection. Too high reduces comfort and grip, too low increases rolling resistance and puncture risk.

4. Using the Calculator

Tips: Enter your total weight (rider + bike) in kg and your tyre width in mm (typically 23-32mm for road bikes). The calculator works best for standard road bike setups.

5. Frequently Asked Questions (FAQ)

Q1: Should I use the same pressure front and rear?
A: Typically, rear pressure should be 5-10% higher than front due to weight distribution.

Q2: How does tyre pressure affect performance?
A: Higher pressure reduces rolling resistance but decreases comfort and grip. Lower pressure improves comfort and grip but may increase rolling resistance.

Q3: When should I adjust from the calculated pressure?
A: Adjust for rough roads (lower pressure), smooth surfaces (higher pressure), or personal comfort preferences.

Q4: Does this work for tubeless tyres?
A: For tubeless, you can typically run 10-15 psi lower than the calculated pressure.

Q5: How often should I check my tyre pressure?
A: Check before every ride as tyres naturally lose 1-2 psi per day.
