What is the meaning of the numbers written on tyres, and how to read them?

From the code written on the tyre, we can know the type, size, weight bearing capacity, speed index etc. of the tyre.

Tire width is measured in millimeters. For example, a 195/55 R16 tire has a width of 195 millimeters, a height of 55%, and a rim size of 16 inches.

The load index of a tire tells how much weight the tire can carry. Load index is a number that ranges from 80 to 270.

The speed index of a tire tells the maximum speed at which the tire can run. For example, a tire with a V speed index can run at a maximum speed of 240 km/h.

Tire air pressure is important to its safety and performance. Tire pressure is determined according to the size of the tyre.
