How do I find my tyre size?

Locating your tyre size

Your tyre size specifies the exact tyres that are compatible with your vehicle, and there are several simple methods to check the tyre size that don't require expert knowledge.

Searching by registration (the quickest method)

The quickest way is to type your vehicle registration at the homepage of Tyres.co.uk. Our system accesses DVLA vehicular data and automatically retrieves the correct tyre size. Within seconds you will see all compatible tyres for your vehicle and won't have to do any manual verification.

Check the tyre sidewall

If you want to check this yourself, look at the sidewall of any of your existing tyres. You should see a sequence of numbers and letters, for example, 205/55 R16 91V. Here's what each part means:

• 205 = Tyre width in millimetres
• 55 = Aspect ratio. This means sidewall height as a percentage of the width
• R = Radial construction, which is standard for modern car tyres
• 16 = Rim diameter in inches
• 91 = Load index (i.e. the maximum weight each tyre can carry)
• V = Speed rating (i.e. maximum safe speed for the tyre)

Other places to find your tyre size

If the sidewall is hard to read, you can also find the recommended size in the following places:

• A sticker on the inside of the driver's door frame, or on the fuel filler flap
• Your vehicle owner's handbook under the tyre specification section
• The vehicle manufacturer's website, using your model and year
