1. What is a Tyre Pressure Calculator?

Definition: This calculator estimates the recommended tyre pressure based on vehicle model, load, and speed conditions.

Purpose: It helps vehicle owners maintain optimal tyre pressure for safety, fuel efficiency, and tyre longevity.

2. How Does the Calculator Work?

The calculator determines pressure based on:

Where:

• \( P \) — Recommended tyre pressure (psi)
• Vehicle model — Determines base pressure requirements
• Load — Additional weight requires higher pressure
• Speed — High speeds may require adjusted pressure

Explanation: The base pressure is adjusted based on load and speed conditions to maintain optimal tyre performance.

3. Importance of Correct Tyre Pressure

Details: Proper tyre pressure ensures safety, improves fuel efficiency by 3-5%, extends tyre life, and maintains optimal handling.

4. Using the Calculator

Tips: Enter your exact vehicle model, current load (including passengers and cargo), and typical driving speed. Check your owner's manual for manufacturer recommendations.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find manufacturer's recommended pressure?
A: Check your vehicle's door placard, fuel filler flap, or owner's manual.

Q2: Should I check pressure when tyres are cold?
A: Yes, always check pressure when tyres are cold (not driven for 3+ hours) for accurate readings.

Q3: How often should I check tyre pressure?
A: At least once a month and before long trips.

Q4: Does temperature affect tyre pressure?
A: Yes, pressure changes about 1 psi for every 10°F (5.6°C) temperature change.

Q5: What's the danger of incorrect pressure?
A: Underinflation causes overheating and blowouts, while overinflation reduces traction and causes uneven wear.
