11.3. Check of pressure of air and a condition of tyres

PERFORMANCE ORDER

1. Check up pressure of air in tyres, at least, once a month and before each distant trip, thus it is not necessary to forget to measure pressure of air and in a spare wheel. 2. Lowered or air elevated pressure in tyres reduces term of their service and worsens road performance of the car. 3. Too low pressure of air in tyres conducts to the raised expense of fuel. 4. On cars establish only radial tyres. 5. In radial tyres of a thread of a cord are located on the least way between tyre boards. The brekernyj belt surrounds a thin and elastic skeleton and provides stability of the tyre. 6. In бескамерных tyres the chamber is replaced with the vulcanized inside layer with high air impermeability. The board of such tyre should be established on a disk rim reliably and tightly. Absence of the chamber in the tyre reduces weight of a wheel and simplifies its installation on a disk rim. 7. Pressure of air in tyres should be checked always at cold tyres. At air elevated pressure in нагретых tyres it is not necessary to let the air out from the tyre. At considerable change of loading of the car it is necessary to change accordingly pressure of air in tyres. 8. For pressure measurement in tyres use a manometre. 9. Check up that there are no leaks of air from the gate. Unscrew a cap from the gate. Put on the gate of a few saliva. At vial formation screw up the gate a cap underside. The prevention For a gate tightening to use only a metal cap. 10. Repeatedly check up the gate. At a further education of vials and at impossibility доворачивания the gate, the gate replace. Necessarily screw a cap. 11. Check up depth of drawing of a protector. Depth of drawing of a protector: Standard tyres: 1,6 mm Winter tyres: 50 % of a protector 12. The tyre should be replaced in the presence of deep cracks, damages, deformation or spotty deterioration. Pay attention to any signs of non-uniform deterioration of tyres.

Kinds and causes of wear of a protector of the tyre

Characteristic kind of deterioration	Plausible reason	Elimination method
Lateral deterioration of a protector	Insufficient pressure in the tyre (bilaterial deterioration of a protector) Wrong disorder of forward wheels (unilateral deterioration of a protector) Passage of turns at great speed	Check up pressure in tyres and restore to the normal Repair or replace suspension bracket details Move with moderate speed
Deterioration of the central part of the tyre	Elevated pressure in tyres	Check up pressure in tyres and restore to the normal
Cross-section angular deterioration	Wrong convergence of wheels	Adjust a convergence of wheels
Non-uniform deterioration	Infringement of disorder of wheels or longitudinal angle of slope of an axis of turn Abnormal work of a forward suspension bracket Infringement of balancing of a wheel Ovality of a wheel disk or brake drum	Repair or replace suspension bracket details Repair or replace suspension bracket details Отбалансируйте a wheel Pierce or replace a brake drum Repair or replace a wheel disk
