Check of a condition of tyres and pressure in them. A designation of tyres and disks of wheels. Rotation and replacement of wheels Depending on model and equipment tyres and disks of the various sizes can be established. Disks have depth запрессовки 38 mm. Depth запрессовки is a distance from the middle of a disk to a persistent surface of a wheel on a brake disk or a drum. Bolts of a wheel for steel and легкосплавных disks have the identical sizes.
At a sports manner of driving it is recommended to increase pressure in forward and back tyres on 0.2 атм. At pressure increase it is necessary to start with a base-line value for various conditions of loading. Winter tyres as a rule have pressure on 0.2 атм. Above than summer. It is necessary to consider recommendations of manufacturers of winter tyres. As winter tyres have restriction on speed, in sight of the driver the tablet with instructions of the maximum speed should be strengthened. Designations of disks Example: 6 J х 15 6 — width of a disk in inches J — a letter designation of height and a contour onboard закраины disk rims х — a 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 a landing shelf of a disk: 0.5 mm. Designation of tyres Example: 195/70 R 14 89 H 195 — width of the tyre in mm /70 — the relation of height to width (the height of cross-section section of the tyre makes 70 % from width) If separate data on the relation of width to height are absent (for example, 175 R 14), means it is a question of "the normal" relation. It makes 82 %. Н — a class of speed, Н: to 210 km/h (on new tyres it is resulted not always). R — a radial design 14 — the size of a disk in inches 89 — load-carrying capacity parametre
Н — a designation of admissible maximum speed. The letter of speed stands up for in the size of the tyre. Symbols of speed concern as 6.6 Indicators of deterioration of a protector of the tyre to depth of 1.6 mm are in the places designated on sidewallsе TWIк summer, and to winter tyres. Letter designations of speed are resulted in Specifications. Date of manufacturing of the tyre Date of manufacturing of the tyre costs on the tyre in a code of the manufacturer Example: DOT CUL2 UM8 019 TUBELESS DOT — Department of Transportation (the Ministry of Transport of the USA) CU — reduction of the name of the manufacturer L2 — The size of the tyre UM8 — Tyre execution 4600 — manufacturing date - 46th working week 2000 TUBELESS — бескамерная (TUBETYPE - the tyre with the chamber) Regular check of a condition of tyres will allow you to avoid the troubles connected with stops in a way because of the lowered wheel. Besides, such checks give the valuable information on possible problems with a steering and a suspension bracket before occurrence in them of serious damages.
Pay attention to any unusual deterioration of protectors. Such defects of a protector as cavities, cambers, уплощения and stronger deterioration on the one hand specify in infringement of corners of installation of forward wheels and-or wheel balancing. At revealing any of the listed defects it is necessary to address for their updating in шиномонтажную a workshop. Carefully check the tyre on presence of cuts, punctures and got stuck nails or buttons. Sometimes after протыкания tyres a nail it still some time holds pressure or lowers very slowly. At suspicion on presence such a slow puncture at first check up tightness of a nipple of the gate of a rating. Then examine a protector on presence of the got stuck strangers of subjects or the punctures repaired earlier again passing air. If there is a suspicion that there is a puncture, to make sure of its presence it is possible, having moistened a suspected site with soap water. In the presence of leak the solution will start to bubble. If not too big, the tyre it is usually possible to repair a puncture in any шиномонтажной a workshop. Carefully examine internal lateral surfaces of tyres on presence on them of signs of leak of a brake liquid. If those are available, immediately check up brake system. Maintenance in tyres of correct pressure increases term of their service, helps to save fuel and improves the general comfort of movement. The special manometre is necessary for pressure check.
Always check pressure upon cold tyres (i.e. to a trip on the car). If to check pressure on warm or разогретых tyres, it will lead to overestimate of indications of a manometre because of thermal expansion of tyres. In this case never it is necessary to lower pressure since after cooling of the tyre it will appear below 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 manometre 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 a dirt and a moisture. Check up pressure in all four tyres 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 tyres Check of pressure of air should be spent only on cold tyres.
Pressure of air in tyres is checked once a month, and also at service carrying out (including spare a wheel). Besides, pressure of air are necessary for checking before each long trip since temperature loading on tyres in this case increases. Necessary pressure of air in tyres is resulted on a label which is on an inside of a cover of a fuel tank.
Pressure of air of narrow tyres of a spare wheel is specified on sidewallsе a disk. Pressure of air in tyres changes depending on change of temperature of air on 10С approximately on 0.1 атм. It should be considered at monitoring procedure of pressure of air in tyres in garage — especially in the winter. Example: Temperature in garage nearby 20С Temperature of external air nearby 0С Established pressure of air in tyres = the specified pressure of air 0.2 атм. Values of pressure of air in the tyres, resulted for small loading of the car, are the minimum values providing comfortableness of movement. Air elevated pressure in the tyres, provided at the raised loading of the car, positively affects controllability of the car as well at small loading and is quite admissible. Smoothness качения thus, however, decreases a little. Check of the gate of tyres
Examples of characteristic deterioration of protectors of tyres Lateral deterioration Wrong disorder of wheels (deterioration on the one hand) Repair or replace suspension bracket details. Too sharp turns Reduce speed! The central deterioration
Superfluous pressure Superfluous pressure in the tyre leads to the accelerated deterioration of the central part of a protector, decrease in coupling with road, to more rigid movement and increase of danger of fatal damage of a slope.Check up and adjust pressure. If you had to pump up tyres for transportation of heavy cargoes to specified for this purpose in Specifications of value of pressure, do not forget after that to pit it at transition in a normal mode of operation. Non-uniform deterioration
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.
Rotation of wheels Rotation of wheels is authorised only at the identical size of forward and back wheels. Rotation of wheels make depending on deterioration of tyres each 5000-10000 km. Thus keep a direction of rotation of wheels. Rotation is necessary for making before occurrence of characteristic signs of deterioration of tyres. A characteristic sign of deterioration at tyres of forward wheels is deterioration of a humeral zone of a protector, and at tyres 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 up and if necessary modify pressure of air in tyres (see above). Bolts of fastening of wheels can ослабнуть if they have not been tightened with the moment of an inhaling specified in Specifications. After replacement of wheels check up the inhaling moment. Spare wheel of the facilitated design At tyre 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, with its normal wheel as it is calculated on the limited run as much as possible to 20 000 km. At replacement of tyres the tyre of a spare wheel can be mounted on the driving wheel if the tyre corresponds to execution of tyres of driving wheels. If the tyre is more senior 6 years, it is recommended to be applied only at tyre damage.
It, therefore, is provided only for short-term use, at observance of the ordered pressure of air in tyres 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 a friable ground use a lining for an automobile jack. Under the car it is necessary to apply to work подставные goats.
