If you are looking for new tyres you should familiarise yourself with the following tyre markings.
Your tyre size can be found on the sidewall of your current tyre and is a sequence of numbers and letters.
The aspect ratio or profile height of the tyre sidewall is expressed as a percentage of the tyre width.
The most common tyre size in the UK is 205/55R16 but there are many variations so it’s important to check your existing tyre or to check your vehicle handbook to ensure the right tyre size has been installed. This displays the width of the tyre in millimetres.
A tyre marked 225 will measure 225mm across the tread from sidewall to sidewall.
The tyre DOT corresponds to the manufacturing date.
It consists of four digits that indicate the week and year of production.
