1. What is a Road Bike Tyre Pressure Calculator?

Definition: This calculator estimates the optimal tyre pressure based on rider weight, tyre size, and riding style factors.

Purpose: It helps cyclists determine the best tyre pressure for performance, comfort, and safety.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Tyre pressure (psi)
• \( W \) — Rider weight (kg)
• \( F \) — Riding factor (1.1-1.7)
• \( T \) — Tyre size (mm) normalized to 25mm

Explanation: The rider weight is multiplied by a riding style factor, then adjusted for tyre size.

3. Importance of Proper Tyre Pressure

Details: Correct pressure affects rolling resistance, grip, puncture protection, and ride comfort.

4. Using the Calculator

Tips: Enter your weight in kg, tyre width in mm (typically 23-32mm), and select your riding style.

5. Frequently Asked Questions (FAQ)

Q1: Why does tyre size affect pressure?
A: Wider tyres distribute weight over more surface area, requiring lower pressure for the same support.

Q2: What riding factor should I choose?
A: Use 1.5 for general road riding, lower for comfort (1.1), higher for racing (1.7).

Q3: Should I adjust for tubeless tyres?
A: Yes, reduce pressure by 5-10% for tubeless setups as they run lower pressures safely.

Q4: How often should I check pressure?
A: Before every ride, as tyres naturally lose 1-2 psi per day.

Q5: What about front/rear pressure differences?
A: Rear tyre typically needs 5-10% more pressure due to weight distribution.
