What size are my tyres?

how old are my tyres

You may be wondering what size your tyres are if you are looking to replace a punctured tyre, purchase new seasonal tyres or simply replace old tyres which have been exposed to wear and tear. But how do you know what size tyres your car needs? Our detailed guide has you covered.

What size tyres for my car?

You can locate the size of any tyre by the printed numbers and letters on the side of the tyre – an area also known as the ‘sidewall’. The sidewall contains code comprising of letters and numbers, which when broken down, lets you identify the size of your tyre. So, what do these numbers and letters mean? They are broken down to the following categories:

  • Width
  • Sidewall height
  • Diameter
  • Tread pattern
  • Load index
  • Speed rating

For more information on what the numbers on tyres mean, follow our detailed guide – which breaks down the specific categories by number or letter, and explains what to look out for when checking your own tyre size.

How to find tyre size online

There are also various sites you can use which use your vehicle registration to look up the tyre sizes on your vehicle. The data is held by the DVLA, which then suggests which tyre size is most appropriate for your vehicle.

However, the most reliable way of checking your tyre size is manually – as it’s likely you’ll be replacing an existing tyre on your vehicle directly with a new tyre.
