1. What is the Vittoria Tyre Pressure Calculator?

Definition: This calculator provides recommended tyre pressure based on Vittoria's guidelines for road cycling.

Purpose: It helps cyclists determine optimal tyre pressure for performance, comfort, and safety.

2. How Does the Calculator Work?

The calculator uses Vittoria's recommended formula:

Where:

• \( P \) — Recommended tyre pressure (bar)
• \( W \) — Total weight of rider + bike (kg)

Explanation: The formula scales pressure from 4 bar (at 70kg) to 7 bar (at 100kg) following Vittoria's recommendations.

3. Importance of Correct Tyre Pressure

Details: Proper tyre pressure affects rolling resistance, grip, comfort, and puncture protection. Vittoria recommends 4-7 bar for road cycling.

4. Using the Calculator

Tips: Enter your total weight (rider + bike) in kg (between 70-100kg). The calculator will output the recommended pressure in bar.

5. Frequently Asked Questions (FAQ)

Q1: Why does weight affect tyre pressure?
A: Heavier loads require higher pressure to maintain optimal tyre shape and prevent pinch flats.

Q2: What if my weight is outside 70-100kg?
A: For weights below 70kg, use 4 bar. Above 100kg, consult Vittoria's technical support for specific recommendations.

Q3: Should I adjust for different tyre widths?
A: Yes, wider tyres typically use lower pressures. This calculator is for standard 23-25mm road tyres.

Q4: How often should I check my tyre pressure?
A: Vittoria recommends checking before every ride, as tyres naturally lose pressure over time.

Q5: Does this account for different road conditions?
A: For wet conditions, you might reduce pressure by 0.2-0.5 bar for better grip.
