Load index tires

The load index tires - a numerical expression of maximum load a tire can carry at the rate specified by the corresponding index and at a certain pressure of air in it. Below is a table that identifies the maximum load in kg. However, it should be noted that all indices are loads listed for maximum speed of 210 km / h. For Class V, 240 km / hour for the bus in W and 270 km / h for buses class Y. Above these speeds the maximum load index should be lower. On some buses, especially on the tires ZR-class description of the operating conditions do not apply. In such cases obraschaytsya the manufacturer and find out the maximum load value. In accordance with European regulations (ECE-R54), all tires designed for commercial vehicles should be marked "Service Description" ("Operating"), deposited near the size tire. This marking is the code that shows the limits of load and speed and includes a "load index" for single and dual wheels and an "index rate" (for example, 102/100R). Load indices and speed are applied to both the tire sidewall. The first figure shows the load bus at a single installation, and the second digit corresponds to Dual wheels. Additional markings may be used to refer to the corresponding tire loads of other higher speeds. This additional marking circled.
