Designations of disks
Example: 6 J x 15
6 width of a disk in inches
J alphabetic reference of height and contour onboard закраины disk rims
x designation of an integral deep disk
15 diameter of a disk in inches
Admissible lateral palpation on onboard закраине a disk: 0.8 mm;
Admissible radial palpation on the landing shelf of a disk: 0.5 mm.
Designation of tires
Example: 195/70 R 14 89 H
195 width of the tire in mm
/70 the relation of height to width (the height of cross-section section of the tire makes 70 % from width)
If hotel data on the relation of width to height are absent (for example, 175 R 14), mean are a question of the "normal" relation. It makes 82 %.
N class of speed, N: to 210 km/h (on new tires it is brought not always).
R radial design
14 size of a disk in inches
89 parameter of loading capacity
|
|
If between data 14 and 89 there is M+S designation, it is a question of tires with a winter protector. |
N designation of admissible maximum speed.
The letter of speed stands up for in the size of the tire. Symbols of speed belong both to summer, and to winter tires.
Alphabetic references of speed are given in Specifications.
Date of manufacturing of the tire
Date of manufacturing of the tire costs on the tire in a code of the producer
Example: DOT CUL2 UM8 of 4600 TUBELESS
DOT Department of Transportation (Ministry of Transport of the USA)

Regular check of a condition of tires will allow you to avoid the troubles connected with stops in a way because of the lowered wheel. Besides, such checks give valuable information on possible problems with a steering and a suspension bracket before emergence in them serious damages.
Pay attention to any unusual wear of protectors. Such defects of a protector as cavities, cambers, uploshcheniye and stronger wear on the one hand indicate violation of corners of installation of forward wheels and/or wheel balancing. At identification any of the listed defects it is necessary to address for their adjustment in a shinomontazhny workshop.
Carefully check the tire on existence of cuts, punctures and got stuck nails or buttons. Sometimes after a tire protykaniye a nail it still some time holds pressure or lowers very slowly.
At suspicion on existence such «a slow puncture» at first check tightness of a nipple of the gate of a rating. Then examine a protector on presence at it got stuck strangers of subjects or closed up before the punctures which have started over again to pass air. If there is a suspicion that there is a puncture, to make sure of its existence it is possible, having moistened a suspected site with soap water. In the presence of leak solution will start to bubble. If not too big, the tire it is usually possible to repair a puncture in any shinomontazhny workshop.
Carefully examine internal lateral surfaces of tires on existence of signs of leakage of brake liquid on them. If those are available, immediately check brake system.
Maintenance in tires of the correct pressure increases term of their service, helps to save fuel and improves the general comfort of movement. The special manometer is necessary for check of pressure.
Recommendations: Always keep an exact manometer in the ware box. Indications of the manometers which have been built in nozzles of air hoses at stations of service, often happen inexact.
Always check pressure on cold tires (i.e. to a trip on the car). If to check pressure on the warm or warmed-up tires, it will lead to overestimate of indications of a manometer because of thermal expansion of tires. In this case never it is necessary to lower pressure since after tire cooling it will appear lower than norm.
Screw together a protective cap from the gate of a rating acting from a disk of a wheel or from a cap of a nave, then densely press to the gate a manometer nozzle. Consider instrument readings and compare them with recommended in Specifications. Do not forget to establish into place a protective cap for hit prevention in the mechanism of a nipple of dirt and moisture. Check pressure in all four tires and if necessary pump up them to the recommended value of pressure.
Do not forget to support demanded pressure and in a spare wheel.
Check of pressure of air in tires
Check of pressure of air should be carried out only on cold tires.

Examples of characteristic wear of protectors of tires
Lateral wear
|
|
|
Insufficient pressure in the tire leads to its overheat at movement owing to an excessive deflection therefore the protector does not nestle sufficiently on a road surface. It leads to loss of coupling with the road and to excessive wear of a protector, not to mention danger of an exit of the tire out of operation as a result of an overheat.
Check and adjust pressure.
Wrong disorder of wheels (wear on the one hand)
Repair or replace suspension bracket details.
Too sharp turns
Reduce speed!
Central wear
|
|
|
Superfluous pressure
Superfluous pressure in the tire results in the accelerated wear of the central part of a protector, decrease in coupling with darling to more rigid movement and increase of danger of fatal damage of a slope.
Check and adjust pressure.
If you had to pump up tires for transportation of heavy cargoes to specified for this purpose in Specifications of value of pressure, do not forget after that to pit it upon transition to a normal mode of operation.
Non-uniform wear
|
|
|
Tires of forward wheels can non-uniformly wear out as a result of violation of adjustment of corners of installation of wheels. To check and adjust corners of installation it is possible for a moderate payment in the majority of shinomontazhny workshops.
Wrong disorder or выбег
Repair or replace suspension bracket details.
Defect of a suspension bracket
Repair or replace suspension bracket details.
Wheels are debalanced
Make balancing of wheels.
Convergence of forward wheels is incorrectly established
Adjust corners of installation of forward wheels.
|
|
The Obtrepannost of edges of a pattern of the protector, being a wear sign, best of all comes to light to the touch. |
Rotation of wheels
Rotation of wheels is authorized only at the identical size of lobbies and back wheels.
Rotation of wheels make depending on wear of tires each 5000-10000 km. Thus keep the direction of rotation of wheels.
Rotation is necessary for making before emergence of characteristic signs of wear of tires. A characteristic sign of wear at tires of forward wheels is wear of a humeral zone of a protector, and at tires of back wheels — the protector middle.
At each rotation of wheels it is necessary to clear carefully them from the inside. After rotation of wheels check and if necessary modify pressure of air in tires (see above).
Bolts of fastening of wheels can weaken, if they were not tightened with the moment of an inhaling specified in Specifications. After replacement of wheels check the inhaling moment.
Apply only firm bolts of fastening «MB» designated by a star of "Mercedes-Benz". Other bolts can unscrew.
Spare wheel of the facilitated design
At tire damage the spare wheel of the facilitated design can be used as a normal wheel; it is recommended to replace as soon as possible, however, it with a normal wheel as it is calculated on limited run as much as possible to 20 000 km.
At replacement of tires the tire of a spare wheel can be mounted on the driving wheel if the tire corresponds to execution of tires of driving wheels. If the tire is more senior than 6 years, it is recommended to be applied only at tire damage.
Models with tires 245/45R18:
If the spare wheel of the facilitated design is mounted, owing to the various sizes of tires it is necessary to reckon with change dynamic property of the car. Conform style of driving to a road situation.
As soon as possible replace a spare wheel of the facilitated design with a usual wheel.
Models with an AMG firm complete set
There is a danger of failure!
If the spare wheel of the facilitated design is mounted, owing to the various sizes of tires it is necessary to reckon with change of dynamic properties of the car. Conform style of driving to this situation.
It, therefore, is provided only for short-term using at observance of the ordered pressure of air in tires and the maximum speed of 80 km/h.
Operation with more, than one spare wheel of the facilitated design is inadmissible.
Replacement of wheels
The automobile jack is intended only for short-term lifting of the car at wheel replacement.
The basic platform of an automobile jack should be firm and equal. In case of friable soil use a lining for an automobile jack.
Under the car it is necessary to apply a false trestle to work.
