1. What is a Tyre Pressure Calculator for Australia?

Definition: This calculator determines the optimal tyre pressure based on vehicle load, tyre specifications, and Australian conditions.

Purpose: It helps caravan owners and vehicle operators maintain proper tyre pressure for safety and performance, especially important in Australia's varied terrain.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Recommended tyre pressure (psi)
• \( max\_P \) — Maximum tyre pressure (psi)
• \( max\_load \) — Maximum load per tyre (kg)
• \( actual\_load \) — Actual vehicle load (kg)
• \( num\_wheels \) — Number of load-bearing wheels

Explanation: The formula proportionally adjusts pressure based on the actual load compared to maximum capacity.

3. Importance of Proper Tyre Pressure

Details: Correct tyre pressure ensures safety, optimal fuel efficiency, even tyre wear, and proper handling - especially critical for caravans in Australia's harsh conditions.

4. Using the Calculator

Tips: Enter the tyre's maximum pressure and load rating (found on sidewall), actual vehicle/caravan load, and number of wheels. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculator specific to Australia?
A: Australia's extreme temperatures and long distances make proper tyre pressure especially important for safety.

Q2: Where do I find max pressure and load ratings?
A: These are stamped on the tyre sidewall - look for "Max Load" and "Max Press" values.

Q3: Should I adjust pressure for hot weather?
A: Yes, in high temperatures (above 30°C), consider reducing pressure by 2-3 psi from the calculated value.

Q4: How often should I check caravan tyre pressure?
A: Before every trip and at least monthly when in storage, as caravan tyres are particularly prone to pressure loss.

Q5: Does this work for all vehicle types?
A: Primarily designed for caravans and light vehicles. Heavy trucks may require different calculations.
