1. What is the SILCA Tire Pressure Calculator?

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

Purpose: Helps cyclists achieve the perfect balance of speed, comfort, and traction by optimizing tire pressure for their specific setup.

2. How Does the Calculator Work?

The calculator uses SILCA's advanced algorithm that considers:

• Total system weight (rider + bike + gear)
• Tire width in millimeters
• Terrain type (smooth road, rough road, gravel, or off-road)
• Weight distribution between front and rear wheels

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

3. Importance of Proper Tire Pressure

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

4. Using the Calculator

Tips:

• Measure your total system weight accurately (including bike and gear)
• Use actual measured tire width (may differ from labeled size)
• Select terrain that matches your typical riding surface
• Default weight distribution is 40% front / 60% rear for road bikes

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 often should I recalculate tire pressure?
A: Whenever your weight, tires, or typical terrain changes significantly.

Q3: Are these pressures suitable for tubeless setups?
A: Yes, but you may reduce by 5-10% for tubeless as they typically run lower pressures.

Q4: Why do wider tires need lower pressure?
A: Wider tires distribute weight over a larger contact patch, requiring less pressure to support the same weight.

Q5: Should I adjust for wet conditions?
A: Consider reducing pressure by 5-10% in wet conditions for better traction.
