The application of the tyre means which car is most compatible with the said tyre. For example, P marking means the tyre is compatible with passenger cars.


The width of the tyre is the measure of the tyre from sidewall to sidewall which is measurable in millimetres. The wide-width tyre helps in off-roading in hilly areas, grasslands, deserts etc. Whereas narrow-width tyres are more suitable for city streets. The width of the tyre helps with the performance of the vehicle and also impacts the fuel efficiency.


The ratio of width and the height of the tyre is its aspect ratio. The height here is in respect to the percentage of the width. For instance, if the aspect ratio of a tyre is 65. It will mean that the height of your tyre is 65% of the width of the tyre.


The rimmed case of tyres has a different construction. The most common construction is radial construction(R). Other constructions that are also common are bias-ply construction(B) and diagonal construction(D).


The diameter is the diameter of the rim or the height of the rim which is measurable in inches.


The load index tells you the maximum weight that your tyre can bear and still perform optimally. If you put any extra weight than the said load index, it can compromise the sustainability of your tyres. If your tyre has a load index of 75, it means your tyre can carry up to 750kgs.


The speed rating is self-explanatory, it means the maximum speed at which your tyre can perform and sustain. Although the speed rating cannot be accurate but is the average of the speed at which it is safe to drive your vehicle. It is always good to drive carefully and speed limit even when your speed rating is more, as it is safer and according to driving norms.

Above are the main sequence or size codes of your tyre. Besides that, there are a few more specifications which allow you to know more about your tyres, such as:


The SSR marking on the sidewalls of the tyre means the tyre is a self-supporting run-flat tyre. This means your tyre has reinforced walls that offer support in case of a puncture. This also means you will not lose control of your tyre and can drive to a safer place or a nearby auto repair shop.


The M+S marking is common in winter tyres. This marking stands for mud and snow which means these tyres will offer you optimal performance on snowy or muddy roads.


The DOT marking is the stamp of approval from the department of transportation.


The directional arrows come in handy while mounting treads. They provide you with information about the direction in which the tread should be mounting. This is very crucial in the case of directional tyres.
