Tyre Sizes

There are two main purposes of the writing that you'll see on the sidewall of your tyres:

1. To help identify the size and specification of the tyres correctly.
2. To confirm that the tyre has been tested and approved to European and other country safety standards.

The European mandatory is known as 'E' marking. See diagram explaining each part of the tyre reference.

Although not illegal, it is not recommended to have tyres with a lower speed rating or load capacity than the manufacturer recommended tyre specification for your vehicle, or to have a combination of different tyre construction types. Consult your vehicle handbook, which will confirm your vehicles tyre speed and load ratings as well as any additional requirements.
