How to read tyre sizes

Choosing the right tyre size is crucial for your vehicle’s performance, safety, and efficiency. If you’re unsure how to check your tyre size, this guide will walk you through the process step by step.

Where to Find Your Tyre Size

Your tyre size is usually printed on the sidewall of your tyre. You can also find it in your vehicle’s owner’s manual or on a sticker inside the driver’s door frame, glove box, or fuel cap.

Understanding the Tyre Size Format

Tyre sizes are displayed in a standard format, such as 205/55R16 91V. Here’s what each part means:

• 205 – The tyre’s width in millimeters.
• 55 – The aspect ratio, representing the height of the tyre’s sidewall as a percentage of its width.
• R – Radial construction (most modern tyres are radial).
• 16 – The wheel diameter in inches.
• 91 – The load index, indicating the tyre’s weight capacity.
• V – The speed rating, showing the maximum speed the tyre can handle safely.

Checking Your Tyre Size for Replacement

When replacing tyres, ensure the new ones match the specifications recommended by the vehicle manufacturer. Using the wrong tyre size can affect handling, fuel efficiency, and safety.

Additional Tips

• Always check all four tyres to confirm they match.
• If upgrading to a different size, consult a tyre expert.
• Consider seasonal and performance needs when choosing tyres.
