Check of a condition of tires and pressure in them. Designation of tires and disks of wheels. Rotation and replacement of wheels Depending on model and equipment tires and disks of the various sizes can be established. Disks have depth of a press fitting of 38 mm. Depth of a press fitting is a distance from the disk middle to a persistent surface of a wheel on a brake disk or a drum. Wheel bolts for steel and light-alloy wheels have the identical sizes.
At a sports manner of driving it is recommended to increase pressure in lobbies and back tires by 0.2 atm. At increase in pressure it is necessary to start with a base-line value for various conditions of loading. Winter tires as a rule have pressure upon 0.2 atm. above than summer. It is necessary to consider recommendations of manufacturers of winter tires. As winter tires have restriction till speed, in sight of the driver the plate with the indication of the maximum speed should be strengthened. Designations of disks Example: 6 J x 15 6 — width of a disk in inches J — an alphabetic reference of height and a 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 separate 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 — a class of speed, N: to 210 km/h (on new tires it is brought not always). R — a radial design 14 — the size of a disk in inches 89 — loading capacity parameter
N — designation of admissible maximum speed. The letter of speed stands up for in the size of the tire. Symbols of speed belong as 6.6 Indicators of wear of a protector of the tire to depth of 1.6 mm are in the places designated on боковине by TWIK by 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 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 tire UM8 — tire execution 4600 — manufacturing date - the 46th working week 2000 TUBELESS — tubeless (TUBETYPE - the tire with the chamber) 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 of the got stuck strangers of subjects or the punctures repaired before which are again passing 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.
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.
Pressure of air in tires is checked once a month, and also at carrying out service (including spare a wheel). Besides, pressure of air are necessary for checking before each long trip since temperature load of tires in this case increases. Necessary pressure of air in tires is given on a sticker being on inside of a cover of a fuel tank.
Pressure of air of narrow tires of a spare wheel is specified on боковине a disk. Pressure of air in tires changes depending on change of temperature of air on 10°С approximately on 0.1 atm. It should be considered at monitoring procedure of pressure of air in tires in garage — especially in the winter. Example: Temperature in garage near + 20°С Temperature of external air near 0°С Established pressure of air in tires = the specified pressure of air + 0.2 atm. Values of pressure of air in the tires, given for small loading of the car, are the minimum values providing comfortableness of movement. The air elevated pressure in the tires, provided at the raised loading of the car, positively affects controllability of the car as well at small loading and is quite admissible. Smoothness of a kacheniye thus, however, decreases a little. Check of the gate of tires
Examples of characteristic wear of protectors of tires Lateral wear 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
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 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. 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.
It, therefore, is provided only for short-term use, 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.
