The correct tyre size for your vehicle can be found on the sidewall of your current tyres or in your vehicle’s owner’s manual. The tyre size is represented by a combination of numbers and letters, such as 205/55 R16, where ‘205’ is the tyre width in millimetres, ’55’ is the aspect ratio, ‘R’ indicates radial construction, and ’16’ is the wheel diameter in inches. It’s important to match this size when purchasing new tyres to ensure proper fit and performance.
