Understanding Tyre Sizes

Choosing the correct tyre size is important for your vehicle’s safety, comfort, fuel efficiency, and overall performance. Every vehicle is designed to use specific tyre sizes, and using the wrong size can affect handling, braking, and even damage your vehicle over time.

Where Can I Find My Tyre Size?

You Can Usually Find Your Tyre Size In These Places:

Inside The Driver’s Door Frame

In Your Vehicle Owner’s Manual

On A Sticker Inside The Fuel Cap

What Does A Tyre Size Mean?

A - 205 (Tyre Width)

This is the width of the tyre in millimetres from one sidewall to the other.

205 = 205mm Wide

Wider Tyres Usually Provide:

Better grip

Improved handling

Sportier appearance

B - 55 (Profile / Aspect Ratio)

This is the height of the tyre sidewall as a percentage of the tyre width

55 Means The Sidewall Height Is 55% Of 205mm

Lower Profiles Generally Offer:

Better cornering

Sportier handling

Higher Profiles Generally Offer:

More comfort

Smoother driving

R (Radial Construction)

Most modern tyres are radial tyres because they:

Last longer

Improve fuel efficiency

Provide better road grip

C - 16 (Rim Size)

This tells you the wheel size the tyre fits.

16 Means The Tyre Fits A 16-Inch Rim

GOLDEN RULE OF THUMB

Your tyre and rim size must always match.

This number shows how much weight the tyre can safely carry

A higher load index means:

More carrying capacity

Better support for heavier vehicles
