If you ask the average person the size of the tyres they have on their car, most people won’t be able to tell you right away. In fact, many people may not even know where to look to find their tyre size or what any of the information means.

If you are shopping for tyres, knowing the size you need is important if you want to get the right tyres for your vehicle. There are a couple of ways you can find out this information.

What Size are My Tyres?

The easiest way to find the tyre size you need is by using our search by registration facility, but you will still have to double check the size before ordering. Alternatively, you can look in your car manual to find the information about your tyres.

You can also look at the label inside the driver’s side door. This normally has the tyre information for your car printed on it. Lastly, you can look at the tyres that you currently have on your car.

The tyre size is printed right on the tyre itself. However, if your tyres are old and wearing you may not be able to read it very easily. If you struggle to read the size on the wall of the tyre, you may want to check with your mechanic to see what size of tyre you need for your car.

Tyre Size Guide

What Size Tyres do I Need?

If your tyres display numbers such as 167/40R 12 79 H, this is the tyre type for your car. In this example, the 167 is what the width of your tyre is in millimetres. The 40 indicates the ratio or profile of your tyres. The letter R lets you know what type of tyre it is - in this case, the R stands for radial. The number 12 is the diameter of the wheel rim in inches.

The next number, the 79, is the load index of the tyre, letting you know the maximum weight the tyres can safely hold up. The last letter, H, indicates the maximum speed rating for the tyres. The ratings go from A to Y and go up in increments, with H having a maximum speed of 130.

Take the time to learn your tyre size so you can be sure that you always get the right tyres for your car for the best performance and safety.
