1. What is a Caravan Tyre Pressure Calculator?

Definition: This calculator estimates the optimal tyre pressure for caravans based on weight distribution and tyre specifications.

Purpose: It helps caravan owners in Australia determine the correct tyre pressure for safe towing and optimal tyre performance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Tyre pressure (kPa)
• \( W \) — Total caravan weight (kg)
• \( T \) — Number of tyres
• \( L \) — Load capacity per PSI (kg/PSI)
• \( F \) — Safety factor (typically 1.1)

Explanation: The caravan weight is divided by number of tyres to get weight per tyre, then divided by load capacity to get base pressure, and finally multiplied by a safety factor.

3. Importance of Correct Tyre Pressure

Details: Proper tyre pressure ensures even weight distribution, prevents blowouts, improves fuel efficiency, and extends tyre life.

4. Using the Calculator

Tips: Enter the caravan weight in kg, number of tyres (default 4), load per PSI (default 68.95 kg/PSI), and safety factor (default 1.1). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical load capacity per PSI?
A: Most caravan tyres have a load capacity of about 68.95 kg/PSI (or 10 kg/kPa), but check your tyre specifications.

Q2: Why include a safety factor?
A: The safety factor (typically 1.1) accounts for uneven weight distribution and dynamic loads while towing.

Q3: Should I use this for all types of caravans?
A: This works for most standard caravans. For heavy-duty or off-road caravans, consult your manufacturer.

Q4: How often should I check tyre pressure?
A: Check before every trip and at least monthly when not in use.

Q5: Does this work for other vehicles?
A: The same principle applies, but load capacities differ - always check your vehicle's specifications.
