What each code section stands for:
This code is a breakdown of four key factors when determining tyre size and type:
Width - The width of the tyre in millimetres.
Profile - The height of the tyre sidewall as a percentage of the tyre width.
Rim Size - The diameter of the tyres inner rim, in inches.
Speed Rating - The maximum recommended speed for the tyre at full load.
For example, a tyre with the code 205 / 55 R16 79T would have a tyre width of 205 millimetres, a sidewall height of 55% of the width, a 16-inch inner rim size and a speed rating of T.
Always check your existing tyres
If you are searching for your tyres online using your vehicle registration number and your existing tyre size differs from the one displayed in the tyre results, simply update the relevant tyre size details and search again.
Important note: Some manufacturers specify different front and rear tyre sizes. Please check the size of tyre you want to replace before ordering.
How to check tyre tread
Most tyres have a tread wear indicator located on the inner groove of the tread. It is important to check the whole tyre meets this minimum marker, as any part of the tyre tread that does not meet this marker may result in your tyre being illegal. Current UK Legislations require a minimum tyre tread of 1.6mm by law. The penalty for breaching this is a fine of up to £2500 and 3 penalty points per tyre.
Formula One Autocentres recommend checking your tyres on a weekly basis to ensure tyre pressure and tread meet legal requirements, as well as checking for any damage - as this also can result in your tyre being deemed illegal.
If you want more information on how to check your tyre tread, read our helpful blog post.
If you have any concerns that your tyre(s) may be illegal please call your local Formula One Autocentre - we will be happy to take a look at them for you, free of charge.
