1. What is a Mountain Bike Tyre Pressure Calculator?

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

Purpose: It helps mountain bikers find the ideal tyre pressure for their specific setup and riding conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Tyre pressure (psi)
• \( W \) — Rider weight (kg)
• \( V \) — Tyre volume (width in inches)
• \( F \) — Riding factor (varies by discipline)

Explanation: The rider weight is divided by tyre volume to get base pressure, then multiplied by a riding factor to account for different riding styles.

3. Importance of Proper Tyre Pressure

Details: Correct tyre pressure affects traction, rolling resistance, puncture protection, and overall ride quality.

4. Using the Calculator

Tips: Enter your weight in kg, tyre width in inches, and select your riding style. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why does riding style affect pressure?
A: Different disciplines require different balances between grip and rolling speed.

Q2: What's a typical tyre volume for MTB?
A: Most mountain bikes use tyres between 2.2" and 2.6" width, with 2.4" being common.

Q3: Should I use the same pressure front and rear?
A: Typically, run 1-3 psi less in the front tyre for better traction.

Q4: How do I find my exact tyre volume?
A: Check the sidewall of your tyre - the width is printed there (e.g., 29x2.4").

Q5: Does this include bike weight?
A: No, this is rider weight only. Add 1-2 psi to account for bike weight if needed.
