3.5. Check of a condition of tires and pressure of their rating, rotation of wheels

The conscientious attitude to regular check of a condition of tires will allow the driver to avoid the annoying delays connected with an exit of a wheel out of operation during movement. Besides, on nature of wear of protectors it is possible to reveal beforehand the developments which were at a stage defects of components of a suspension bracket and a steering drive.

Entering into a standard complete set of cars considered in the real Management the wheels equipped with special display tapes, having about 12 mm and being shown on a protector pattern enter width at wear of the last to an admissible limit. The minimum admissible depth of a protector makes 1.6 mm.

To estimate degree of wear of a protector it is possible by means of the special inexpensive adaptation — ask in shops of automobile accessories.

Pay attention to any signs of non-uniform wear of a protector.

PRESSURE OF THE RATING OF THE TYRE DOES NOT SUFFICE

TOO HIGH PRESSURE OF THE RATING OF TYRES

THE SCALY WEAR OF THE PROTECTOR CAUSED BY VIOLATION OF CORNERS OF INSTALLATION OF WHEELS

CONVERGENCE ADJUSTMENT IS BROKEN, OR DISORDER OF WHEELS IS TOO GREAT

CHASHEVIDNYE DEFECTS

The following reasons of formation of chashevidny defects are possible:

  • Tires are too poorly pumped up, or the mechanical deviation (violation of balancing of a wheel or disk deformation) takes place.
  • Weakened fastening of steering drafts of a steering drive, or their tips are worn-out.
  • Components of a forward suspension bracket are damaged or worn-out, or weakened their fastening

Such local defects as a chashevidny wipe, uploshcheniye, etc., are usually obliged by the emergence to violations of corners of installation of forward wheels, or balancing of the last. For identification and elimination of malfunctions the car should be driven away in a specialized workshop of car-care center or on car repair shop.

 PERFORMANCE ORDER

  1. Attentively examine tires of all wheels on existence of cuts, punctures and got stuck in flutes of a pattern of a protector of extraneous subjects. Sometimes the punched wheel during even any time continues to hold in itself air in view of that the subject which has punctured the tire continues to remain thrust in it. Defect of a nipple of the gate of a rating of a wheel can be the reason of a slow spuskaniye of the tire — check a nipple condition.
  1. Attentively examine a protector on existence of the extraneous subjects which have got stuck in it and signs of violation of tightness of landing of repair "jams" by means of which repair of small punctures of the tire is made. To make sure available a puncture rather simply — it is enough to moisten a suspected site of a surface of the tire with solution of soap water — if the puncture takes place, solution will start to bubble. Insignificant punctures on size are usually easily eliminated in shinomontazhny workshops.
  1. Attentively examine internal walls of tires of all four wheels on existence on them потеков brake liquid. In case of identification of those immediately check a condition of the corresponding brake mechanisms and the hydraulic lines connected to them.
  2. Podderzhivaniye of demanded pressure of a rating of tires will allow to prolong essentially service life of wheels, besides, will provide the maximum comfort at movement and let's reduce controllability of the car. Remember that it is correct to measure pressure in the tire by eye it is almost impossible, in particular, if it is a question of tires of a radial design. It is necessary to hold constantly near at hand a suitable manometer — on gas stations and car repair shops it is not necessary to trust indications of measuring instruments of compressors of pumping.
  3. Check pressure of a rating of tires at cold wheels — it is meant that the car passed no more than one mile within the last three hours. Remember that increase of pressure on 0.3 — 0.6 kgfs/cm 2 as a result of a warming up of a wheel is quite natural phenomenon.
  1. Remove from the gate of a rating of a wheel a protective cap and densely press a manometer nozzle to an exhaust outlet of the gate, having wrung out a nipple rod. Consider the read instrument and compare it to standard data, in case of need correct pressure.
  1. Do not forget to screw on a place a protective cap of the gate in order to avoid hit in a moisture and dirt nipple. Check pressure in all wheels, including the spare.

Pressure of a rating запаски is usually much higher than compact type, than at usual wheels.


Rotation колесы


Recommended order of rotation of the wheels completed with tires C НЕНАПРАВЛЕННЫМ with a protector

1 — Left forward

3 — Left back
4 — Right back

Rotation of wheels should be made regularly according to the schedule of routine maintenance of the car, and also at identification of signs of non-uniform wear of protectors. At rotation the car should be lifted over the earth — use a case and check also a condition of components of brake system (see. Check of brake system).

Originators of this Management recommend to make rotation of the wheels equipped with radial tires, according to offered schemes (see the illustrations Recommended an order of rotation of the wheels completed with tires C НЕНАПРАВЛЕННЫМ with a protector and the Recommended order of rotation of wheels, completed with tires With the DIRECTED protector). The majority of models are completed with tires with the directed protector — the directed tires are easy for distinguishing on existence on a lateral wall of the arrow specifying the correct direction of rotation of a wheel. Two tires should enter into a set with the right direction of rotation and two — with left.

The detailed description of procedure of change of wheels — see. Check of brake system. Track reliability of fixing of the car in the lifted situation.

It will be most correct to lift all car over the earth — use for car fixing in the lifted situation less than four props by no means is inadmissible!

On termination of rotation check pressure of a rating of tires, correct it according to standard requirements. Make sure of reliability of fastening of wheels nuts (in an ideal wheel bolts should be tightened a dinamometrichesky key and to make repeated check through 40 km of run).
