1. What is the SILCA Tire Pressure Calculator?

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

Purpose: Helps cyclists achieve the ideal balance of rolling resistance, comfort, and traction for their specific setup.

2. How Does the Calculator Work?

The calculator uses SILCA's formula:

Where:

• \( P \) — Tire pressure (psi)
• \( W \) — Total system weight (rider + bike + gear in kg)
• \( T \) — Tire width (mm)
• \( S \) — Surface/terrain type
• \( D \) — Weight distribution between front and rear

Explanation: The base pressure is calculated from weight and tire width, then adjusted for terrain and weight distribution.

3. Importance of Proper Tire Pressure

Details: Correct pressure affects rolling resistance (speed), comfort, puncture protection, and cornering traction. Too high reduces comfort and grip; too low increases rolling resistance and puncture risk.

4. Using the Calculator

Tips:

• Measure your total system weight accurately
• Use actual measured tire width (may differ from labeled size)
• Select terrain that matches your typical riding surface
• Standard weight distribution is 55% rear/45% front

5. Frequently Asked Questions (FAQ)

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

Q2: How often should I recalculate?
A: Whenever your weight, bike setup, or typical riding surfaces change significantly.

Q3: What about tubeless vs. tubed tires?
A: Tubeless can typically run 5-10 psi lower than tubed tires for equivalent performance.

Q4: Should I adjust for wet conditions?
A: Yes, consider reducing pressure by 5-10% in wet conditions for better traction.

Q5: Why different pressures front and rear?
A: This accounts for typical weight distribution and provides balanced handling characteristics.
