Tyre sizes explained

How to read the numbers on your tyre sidewall.

Then you should be aware of what the tyre size code means.

A considerable amount of research, time and engineering goes into figuring out an accurate tyre size for a particular car model. Therefore, manufacturers strictly prohibit altering tyre size. Wrong tyre size can lead to various tyre-related road accidents and further cause damage to the structural integrity of the vehicle.

So, whether you drive a sedan, hatchback or SUV, we have just the right set of tyres for your car.

Wondering what the complex alphanumeric tyre size code means?

Worry no more. Keep reading to get detailed guidance on the various elements of the tyre size code.

Let us take the following tyre size as an example: 205/55 R16 91H.

This tyre size contains information such as:

205: This number represents the tyre’s width in millimetres.

55: The number 55 denotes the profile height of a tyre, represented in the percentage of its width.

R: Letter ‘R’ denotes radial construction of the particular model. Other tyre construction types include bias-belt (B) and diagonal cross-ply (D).

16: It represents the rim diameter measured in inches.

91: It represents the load index of a tyre. In this case, the tyre can sustain a maximum weight of 1356 lbs when fully inflated.

H: The letter ‘H’ represents that the particular tyre model can have a maximum speed of 130 mph.

Note: For vehicle-specific instructions, read the car’s placard.
