Understanding tyre size meaning
Every tyre has a code inscribed on its sidewall which contains a series of numbers and letters. This size code must be carefully analysed during a replacement to ensure that the right unit has been fitted following manufacturer guidelines.
Let’s take an example: 205/60R15 91V.
- 205 (Section width): First three numbers refer to the width of the tyre measured in millimetres. This unit measures 205 mm across the tyre tread from sidewall to sidewall.
- 60 (Aspect ratio/profile): 60 basically refers to height to the rim’s tread base. It represents the tread width in percent. In this case, it’s 60%.
- R (Radial): In this particular case, R refers to radial-ply-construction. In Britain, most tyres are radial, meaning they have cord plies placed at 90˚ angles to the direction of mobility to provide the tyre with additional strength.
- 15 (Rim): Here, 15 indicates the rim’s diameter of the rim, measured in inches.
- 91 (Load-Index): This refers to the maximum load-carrying capacity of this tyre. It means that this tyre can load a little above 600 kg.
- V (Speed Index): According to the speed index chart, V indicates that this tyre can pick a maximum speed of 149 mph.
