Decoding tyre size

Tyre size is an alphanumeric code embossed on a tyre’s sidewall. It represents the structural and dimensional details of a tyre. Every car comes with a manufacturer recommended tyre size, which is essential for the optimal functioning of the vehicle.

Let us understand this better with the help of an example- Tyre size: 205/55 R16 91V


It represents the width of a tyre in millimetres.


This number indicates the aspect ratio of the tyre. It is the ratio of the sidewall height to the cross-section width.


The letter ‘R’ stands for radial construction. Apart from this, there are other constructions, including Bias Belt ‘B’ and Diagonal Cross-ply ‘D’.


Number 16 denotes the rim diameter of the tyre, expressed in inches.


Letter "V" stands for the speed index of the tyre. This particular tyre model can sustain a maximum speed of 149 mph.

Knowing these symbols, a car owner should read the car tyre manual first to understand the vehicle-specific instructions better.
