4.2.5. Identification ободьев and tires
The identification code is engraved on a rim and contains important data on the size of a rim.
The code can have the full or reduced form (for example, 6 J 16).
Pressure of air in tires, Corsa-C. year of release with 2005 on 2007
It is not allowed at a design with «the raised useful loading».
2) Are resolved only as winter tires.
Each tire can be identified on the basis of its designation.
Characteristics of speed
Conditional value of a permissible load on the tire
For car tires at speed 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.
