Tire load index - Weight index

Load indices and speed rating symbols are shown on both tire sidewalls. The speed rating is the maximum service speed of a tire.

Here is a list of rating indicators and their speed equivalents. Unmarked radial tires are allowed up to a speed of 110 km/h (68 mph). Bias ply tires are confined to 100 km/h (62 mph). Retreaded tires can be run up to a maximum speed of 110 km/h (68 mph), unless they are marked otherwise. Special purpose tires, for specific heavy duty applications must have the respective speed limitations identified on the sidewall. M&S (winter) tires with a lower speed rating than that of the vehicle may be fitted. In some countries it is mandatory that a sticker be placed in the view of the driver indicating the maximum speed of the tire. This speed may not be exceeded while these tires are fitted. This rating system applies to all tire makers.

Load index in this pictures is 89, that means 580kg/one tire

The load index is an industry standard which determines the maximum service load on a tire of a vehicle.
