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

The conscientious attitude to regular check of a condition of tyres will allow the driver to avoid the annoying delays connected with an exit of a wheel out of operation during movement. Besides, on character of deterioration of protectors it is possible to reveal beforehand developments being 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 present Management the wheels equipped with special display tapes, having about 12 mm and shown on a protector pattern enter width at deterioration of the last to an admissible limit. The minimum admissible depth of a protector makes 1.6 mm.

To estimate degree of deterioration 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 deterioration of a protector.

PRESSURE OF THE RATING OF THE TYRE DOES NOT SUFFICE

TOO THE HIGH PRESSURE OF THE RATING OF TYRES

THE SCALY DETERIORATION OF THE PROTECTOR CAUSED BY INFRINGEMENT OF CORNERS OF INSTALLATION OF WHEELS

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

ЧАШЕВИДНЫЕ DEFECTS

Following reasons of formation чашевидных defects are possible:

  • Tyres are too poorly beefy, or the mechanical deviation (infringement of balancing of a wheel or disk deformation) takes place.
  • Ослабло fastening of steering draughts of a steering drive, or their tips are worn out.
  • Components of a forward suspension bracket, or ослабло their fastening are damaged or worn out

Such local defects as чашевидное a wipe, уплощения, etc., balancing of the last are usually obliged by the occurrence to infringements of corners of installation of forward wheels, or. For revealing and elimination of malfunctions the car should be driven away in a specialised workshop of car-care centre or on a car repair shop.

 PERFORMANCE ORDER

  1. Attentively examine tyres of all wheels on presence 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 keep in itself air whereas the subject which has pierced the tyre continues to remain thrust in it. The reason slow спускания tyres defect of a nipple of the gate of a rating of a wheel can be, — check up a nipple condition.
  1. Attentively examine a protector on presence of the extraneous subjects which have got stuck in it and signs of infringement of tightness of landing of repair "stoppers" with which help repair of small punctures of the tyre is made. To make sure available a puncture simply enough, — it is enough to moisten a suspected site of a surface of the tyre with a solution of soap water — if the puncture takes place, the solution will start to bubble. Insignificant punctures on size are usually easily eliminated in шиномонтажных workshops.
  1. Attentively examine internal walls of tyres of all four wheels on presence on them потеков a brake liquid. In case of revealing of those immediately check up a condition of corresponding brake mechanisms and the hydraulic lines connected to them.
  2. Поддерживание demanded pressure of a rating of tyres will allow to prolong essentially service life of wheels, besides, will provide the maximum comfort at movement and will not allow to lower controllability of the car. Remember that correctly to measure pressure in the tyre by eye it is almost impossible, in particular, if it is a question of tyres of a radial design. It is necessary to hold constantly near at hand suitable manometre, — on gaz 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 tyres at cold wheels, — it is meant that the car has passed within last three hours no more than one mile. Remember that increase of pressure upon 0.3—0.6 kgs/sm 2 as a result of a wheel warming up is quite natural phenomenon.
  1. Remove from the gate of a rating of a wheel a protective cap and densely press a manometre nozzle to a gate exhaust outlet, having wrung out a nipple rod. Consider the read instrument and compare it to the 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 compact type usually considerably above, than at usual wheels.


Rotation колесы

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

Composers of the given Management recommend to make rotation of the wheels equipped with radial tyres, according to offered schemes (illustrations the Recommended order of rotation of the wheels completed with tyres With not DIRECTED protector and the Recommended order of rotation of wheels, completed with tyres With the DIRECTED protector see). The majority of models are completed with tyres with the directed protector, — the directed tyres are easy for distinguishing on presence on a lateral wall of the arrow specifying a correct direction of rotation of a wheel. The complete set should include two tyres 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 position.

Will lift most correctly over the earth all car, — use for car fixing in the lifted position less than four props in no event is inadmissible!

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