What is the load index on a tyre?

The tyre load rating defines the maximum load of a tyre moving at the maximum permissible speed. The load rating is expressed by a two or three-digit number and is located on the tyre sidewall. The manufacturer sets the maximum load capacity of the tyre, taking into account the most loaded axle of a vehicle.
