UNdERSTANDING TYRE SIZES
Tyre sizes may seem complicated but it is pretty straightforward when you know what you're looking for. We have put tother a guide so you can understand what numbers on the sidewall of your tyre means because these numbers are key when buying new tyres.
There are fundamental markings on each tyre that you will need to note down in order to get the right tyre size for your vehicle.

The Numbers Explained
A. TYRE WIDTH
This measures the width of your tyre from sidewall to sidewall. The measurement is in millimetres (mm).
B. ASPECT RATIO
This is the ratio of the tyre’s cross-section to its width, expressed as a percentage. An aspect ratio of 65, for example, indicates that the tyre’s height is 65% of its width.
C. WHEEL DIAMETER
This number represents the diameter of the wheel in inches.
D. LOAD INDEX
Your tyre’s load index appears on your sidewall alongside the speed rating. The load index relates to your tyre’s maximum carrying capacity measured in kilograms (kg).
For example, a tyre with a load index of 91 can carry 615kg of weight. A typical passenger car will have a load index of 75 – 105, with each value corresponding to a weight in kilograms. Load ratings and speed ratings appear next to each other as they should be looked at together when you buy a new tyre. When it comes to replacing your tyres, you may be able to put tyres on your car that have a higher load capacity than your manufacturer recommends. However, check first in your vehicle’s manufacturer documentation. If you overload your vehicle, this will place a stress on critical vehicle components including your tyres. This will cause poor handling, increased fuel consumption and may even cause tyre failure.
E. SPEED RATING
The speed rating is the last of the tyre’s sidewall markings, denoted by a letter to the right of the load index number. Each letter represents the maximum speed that tyre can sustain safely under normal conditions. For example, a tyre with a speed rating of V, has a maximum speed of 240 km/h. Speed ratings range from A to Z and also depend on your tyres being correctly inflated and being under the weight capacity as per the load index. When buying new tyres, make sure you match their speed rating with the speed capabilities of your vehicle. Use our Online Tyre Search above to make the whole process as easy as can be.
