1. What is Tyre Pressure Calculation?

Definition: This calculator determines the optimal tyre pressure based on the actual load compared to the tyre's maximum load capacity.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Recommended tyre pressure (psi)
• \( L \) — Actual load per tyre (kg)
• \( M \) — Maximum load rating (kg)
• \( P_{max} \) — Maximum pressure rating (psi)

Explanation: The actual load is divided by the maximum load capacity to get a proportion, which is then multiplied by the maximum pressure rating to determine the recommended pressure.

3. Importance of Proper Tyre Pressure

Details: Correct tyre pressure ensures optimal vehicle handling, braking performance, tyre wear, and fuel efficiency while preventing blowouts.

4. Using the Calculator

Tips: Enter the actual load per tyre in kg, the tyre's maximum load rating (found on sidewall), and the maximum pressure rating (also on sidewall). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find the max load and pressure ratings?
A: These are printed on the tyre sidewall - look for "Max Load" and "Max Pressure" specifications.

Q2: Should I use this for all vehicle types?
A: This works for most vehicles, but always consult your vehicle manual for manufacturer recommendations.

Q3: How often should I check tyre pressure?
A: At least monthly and before long trips, as pressure changes with temperature and over time.

Q4: What if my calculated pressure differs from the vehicle manual?
A: Always prioritize the vehicle manufacturer's recommended pressure over this calculation.

Q5: Does this account for different driving conditions?
A: No, this is a basic calculation. Adjust for heavy loads, high speeds, or off-road conditions as needed.
