Know About Car Tyre Size

A car tyre size is an alphanumeric code imprinted on the tyre sidewalls. The code conveys vital information about a specific tyre.

Let us cite an example to illustrate what the markings denote.

Reference car tyre size: 225/45R18 95 HSSR MOE M+S DOT 36/16

225: This 3-digit number indicates the sidewall width of the tyre in millimetres.

45: The second number refers to the ratio of the sidewalls to the tyre width. In this case, the sidewall ratio is 45, meaning its height is 45% of its width.

R: The alphabet denotes the construction type of a tyre. R stands for radial tyre type. In addition, there are two other types- bias-ply and diagonal constructions.

18: This 2-digit number indicates the wheel rim diameter of a tyre in inches.

95: The value is the load index rating that suggests the maximum weight-bearing capacity of a tyre. Each value is assigned a different maximum weight in pounds. Here 95 means the tyre can carry a maximum weight of 1521 lbs.

H: This alphabet refers to the speed index rating of the tyre. Each alphabet is assigned a different maximum speed value. ‘H’ means that the permissible speed at full load is up to 130 mph.

There are a few other markings on the tyre sidewall you should be aware of. In this case:

• SSR reveals that it is a run-flat tyre.
• MOE stands for Mercedes Original Equipment Extended Mobility.
• M+S is a symbol confirming mud and snow performance.
• DOT 36/16 provides crucial information identifying the place and time of tyre manufacture. 36/16 here indicates the week and year of manufacture.
