Important Notes

Tire designation

For car tires at speeds up to 270 mph in Europe, there is the ECE-R 30 standard. It contains the most important tire characteristics. In addition, there are additional designations for North America.


Tire designation, see figure below, position 9: 185/ 60 R 14 87 T, refers to the radial tyre.

1 - Position of wear indicator (TWI = Tread wear indicator), height 1.6 mm.

2 - Manufacturer.

3 - Indication of special suitability for winter operation.

4 - Designation of the tread pattern.

5 - Designation for tubeless tires (Tubeless).

6 - Estimated service life according to US test (180 = 180%).

7 - Determining the effectiveness of wet brakes (A, B or C) according to the US test.

8 - Determination of heat resistance at higher speeds (A, B or C) according to the US test.

9 - Dimension designation (185/ 60 R 14 87 T).

185 - Tire width in mm (nominal width).

60 - The ratio of the height of the cross section and the width of the tire in percent.

R - Radial design.

14 – Rim diameter in inches [ «].

87 - Symbol for the permissible load on the tire (Load Index) for 545 kg.

T - Speed symbol for a maximum of 190 mph; additional letter encoding, see publication «Tire pressure» KTA 2625/02 or TIS.

10 - Safety instructions when using or installing a tire (US data).

11 - Radial design.

12 - Number and material of layers in the middle of the running surface and sidewall.

14 – Manufacturer's internal code.

15 - Data regarding maximum allowable load and maximum allowable air pressure for North America.


16 - DOT mark in accordance with the directives of the American transport authorities («Department of Transportation» – «Department of Transport»).

17 - DOT mark for manufacturer, tire size and tire design.

18 - Date of manufacture (here is the 1st production week of 2000). This code consists of 4 digits, two for the week and two for the year.

19 - Size designation (as item number 9).

20 - Country of manufacture.
