The size of a tyre is printed onto its sidewall and is defined by three numbers. The first gives the width of the tyre expressed in millimetres, which is followed by the height of the tyre sidewall which is defined as a percentage of the width. The third number is the rim size in inches that the tyre fits, preceded by the tyre designation letter, which defines the tyre construction but does not relate to its size. Additional information includes other aspects such as the load index and speed rating.
