1. What is the SILCA Pro Tyre Pressure Calculator?

Definition: This calculator determines optimal tyre pressure using SILCA's professional algorithm based on total system weight, tire width, terrain type, and weight distribution.

Purpose: Helps cyclists achieve the perfect balance of speed, comfort, and traction by calculating ideal tyre pressures for their specific setup.

2. How Does the Calculator Work?

The calculator uses SILCA's proprietary formula:

Where:

• \( P \) — Tyre pressure (psi)
• \( W \) — Total system weight (rider + bike + gear)
• \( T \) — Tire width (mm)
• \( D \) — Terrain type (smooth, rough, gravel, off-road)
• \( R \) — Weight distribution (% rear)

Explanation: The algorithm considers multiple factors including rider weight, tire volume, surface conditions, and weight distribution between wheels.

3. Importance of Optimal Tyre Pressure

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

4. Using the Calculator

Tips: Enter your total system weight (including bike and gear), tire width in mm, select terrain type, and specify weight distribution (typically 45-55% rear).

5. Frequently Asked Questions (FAQ)

Q1: Why does weight distribution matter?
A: Most bikes carry more weight on the rear wheel, requiring higher pressure there for optimal performance.

Q2: How do I measure my system weight?
A: Weigh yourself with all riding gear, then add your bike weight and any cargo you typically carry.

Q3: What's the best terrain setting for mixed conditions?
A: Choose the predominant terrain type, or calculate for the worst conditions you'll encounter.

Q4: Should I adjust pressure for weather conditions?
A: Yes, consider reducing pressure slightly in wet conditions for better traction.

Q5: How often should I recalculate?
A: Recalculate whenever your weight, tire width, or typical riding conditions change significantly.
