1. What is a Tyre Pressure Calculator UK?

Definition: This calculator provides recommended tyre pressure values for UK vehicles based on vehicle type and load conditions.

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

2. How Does the Calculator Work?

The calculator uses manufacturer-recommended values:

Where:

• \( P \) — Recommended tyre pressure (PSI)
• Vehicle Type — Car, SUV, Van, or Motorcycle
• Load Condition — Normal, Heavy, or Full load

Explanation: The calculator matches your vehicle and load to standard pressure recommendations used in the UK.

3. Importance of Correct Tyre Pressure

Details: Proper tyre pressure ensures better fuel economy, longer tyre life, improved safety, and optimal vehicle handling.

4. Using the Calculator

Tips: Select your vehicle type and typical load condition. For exact values, always check your vehicle's manual or door placard.

5. Frequently Asked Questions (FAQ)

Q1: Why do tyre pressures vary by load?
A: Heavier loads require higher pressure to maintain the tyre's shape and load-bearing capacity.

Q2: How often should I check my tyre pressure?
A: At least once a month and before long journeys. Check when tyres are cold for most accurate readings.

Q3: What's the difference between PSI and BAR?
A: PSI (pounds per square inch) is the imperial unit, while BAR is metric. 1 BAR ≈ 14.5 PSI.

Q4: Should front and rear tyres have different pressures?
A: Often yes, especially for front-wheel drive vehicles or when carrying heavy loads in specific areas.

Q5: Where can I find my vehicle's exact pressure recommendations?
A: Check your vehicle manual, fuel filler flap, or driver's door sill for manufacturer specifications.
