THE GENERAL DATA |
Models Mercedes of the S-class, depending on the equipment, are equipped by tyres and wheels of the various sizes. The size, along with width of a rim, defines also depth запрессовки. Depth запрессовки represents the size from the middle of a rim to a surface прилегания wheel niches to a brake disk.
All disk wheels have запрессованный a ledge which at very sharp driving on turns prevents pressure of a rim on бескамерную the tyre.
If tyres and / or ободья which are not specified in the passport in the car are established, it is necessary to bring them in the passport. For this purpose, as a rule, the permission to their use from firm Mercedes is necessary.
All data on pressure of air is resulted for cold tyres. Increase of pressure resulting to long driving in tyres on 0,2 bar should not be pitted.
Pressure of air in the tyre of a spare wheel corresponds to the maximum pressure at full loading.
Marks of disks
Example: 6 J х 15 Н2 ЕТ31:
6 = width of a rim of a wheel in inches
J = a letter designation of height and a contour of onboard refuelling of a rim
х = a designation of an one-piece rim with the deep basis
15 = diameter of a rim in inches
Н2 = an external and internal profile of a rim with a ledge shoulder
ЕТ31 = depth запрессовки 31 mm.
Marks of tyres
Example:
The letter designation of speed costs after a designation of the size of the tyre. Symbols of a designation of speed concern both to summer, and winter tyres.

Date of manufacturing of tyres
Manufacturing date is specified on the tyre in a code of the manufacturer.
Example: DOT CUL2 UM8 064 TUBELESS
DOT = the ministry of transport of the USA
CU = the reduced designation of the manufacturer of tyres
12 = the size шиныUM8 = a tyre design
064 = manufacturing date = 06 week 1994
= Symbol of current decade (1990 - 1999)
TUBELESS = бескамерная the tyre (TUBETYPE = the tyre with the chamber).
