Please see our guide to finding your tyre size, or alternatively
Tyre sizes are displayed in a standardised format, such as 225/55 R17 97W. The first number (225) represents the tyre width in millimetres, the second number (55) is the aspect ratio (sidewall height as a percentage of width), R indicates radial construction, 17 is the wheel diameter in inches, 97 is the load rating, and W is the speed rating.
Using the correct tyre size is essential for maintaining your vehicle's speedometer accuracy, handling characteristics, and safety systems like ABS and ESP. Incorrect sizes can affect fuel economy, ride comfort, and may even cause legal issues during MOT testing.
