1. What is the SILCA Pro Tire Pressure Calculator?

Definition: This calculator determines optimal tire pressure based on SILCA's proprietary algorithm that considers total 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 and 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
• \( D \) — Weight distribution between front and rear

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

3. Importance of Proper Tire Pressure

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

4. Using the Calculator

Tips: Enter your total system weight (with riding gear), actual tire width (marked on tire), select terrain type, and weight distribution (default 45% front/55% rear).

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculator?
A: It provides a scientifically-based starting point. Fine-tune ±5 psi based on personal preference.

Q3: Should I use measured or labeled tire width?
A: Use actual measured width if possible, as rim width affects mounted tire width.

Q4: Why different pressures for different terrains?
A: Rough surfaces benefit from lower pressures for vibration damping, while smooth roads favor slightly higher pressures.

Q5: How often should I recalculate?
A: Recalculate when changing tire width, significant weight changes, or different terrain.
