1. What is the SILCA Tire Pressure Calculator?

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

Purpose: Helps cyclists find the ideal tire pressure for comfort, speed, and safety based on their specific setup and riding conditions.

2. How Does the Calculator Work?

The calculator uses SILCA's formula:

Where:

• \( P \) — Tire pressure (psi)
• \( W \) — Total system weight (rider + bike + gear)
• \( T_w \) — Tire width (mm)
• \( T_t \) — Terrain type
• \( D_w \) — Weight distribution between front and rear

Explanation: The algorithm calculates a base pressure from weight and tire width, then adjusts for terrain type and weight distribution.

3. Importance of Proper Tire Pressure

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

4. Using the Calculator

Tips: Enter your total system weight (with riding gear), actual tire width (as marked on tire), select terrain type, and weight distribution (typically 40% front for road bikes).

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculator?
A: It provides a good starting point based on SILCA's research, but fine-tuning may be needed for personal preference.

Q3: Should I use the exact tire width marked on the tire?
A: Yes, use the actual measured width if possible, as rim width can affect mounted tire width.

Q4: What's included in "system weight"?
A: Everything the bike carries - rider, bike, clothing, shoes, helmet, water, tools, etc.

Q5: How often should I check my tire pressure?
A: Before every ride for optimal performance, as tires naturally lose air over time.
