4.2.5. Identification ободьев and tires

NOTE The identification code is engraved on a rim and contains important data on the rim size.

NOTE The code can have the full or reduced form (for example, 6 J 16).

It is not allowed at a design with "the increased payload".

2) Are resolved only as winter tires.

Each tire can be identified on the basis of its designation.

For car tires at a speed up to 270 miles/h in Europe there is a norm of ECE-R 30. It contains the most important characteristics of tires. Besides for North America there are additional designations.

Designation of tires, see the drawing below, a position 9: 185/60 R 14 87 T, concern the radial tire.

1 – The position of the index of wear (TWI = Tread wear indicator), height is 1,6 mm.

2 – Manufacturer.

3 – The instruction on special suitability for operation in the winter mode.

4 – Designation of the drawing of a protector.

9 – Designation of the sizes (185/60 R 14 87 T).

185 – Tire width in mm (nominal width).

60 – Ratio of height of cross section and width of the tire as a percentage.

R – Radial design.

14 – Diameter of a rim in inches ["].

87 – A symbol of a permissible load on the tire (Load Index) for 545 kg.

T – a speed Symbol for at most 190 miles/h; the additional alphabetic coding, see the publication "Air Pressure in Tires" KTA 2625/02 or TIS.

10 – Instructions on safety during the using or installation of the tire (this USA).

11 – Radial design.

12 – Quantity and material of layers in the middle of a running surface and a sidewall.

14 – Internal code of the manufacturer.

15 – The data concerning the most permissible load and the most admissible pressure of air for North America.

16 – The sign DOT according to directives of the American governing bodies of transport ("Department of Transportation" – "Department of Transport").

17 – The sign DOT for manufacturer, the size of the tire and execution of the tire.

18 – Date of production (here the 1st production week 2000). This code consists of 4 figures, two correspond to week, and two – year.
