GENERAL INFORMATION

Characteristic type of drawing of a protector at abnormal wear of tires

1. Lateral wear of a protector
Insufficient pressure in the tire (bilateral wear of a protector)
Check pressure and restore to the normal.
Wrong disorder of forward wheels (unilateral wear of a protector)
To repair or replace suspension bracket details.
Strong angular wear of a protector
Go with moderate speed!
2. Wear in the central part of a protector
Too high pressure in tires
Check pressure and restore to the normal. If you had to pump up wheels to limiting pressure in connection with the forthcoming movement with a high speed or with transportation of big cargo, do not forget to reduce subsequently pressure to the normal.
3. Unilateral slanting wear
Wrong convergence of wheels
Adjust a convergence of wheels.
4. Non-uniform wear
Violation of corners of installation of forward wheels, wheels is bad возвращаютсяв the provision of driving on a straight line after turn
To repair or replace suspension bracket details.
Abnormal work of a forward suspension bracket
To repair or replace suspension bracket details.
The raised imbalance of wheels
Otbalansiruyte of a wheel.
Ovality of a rim or brake drum
To pierce or replace a drum, to repair or replace a rim.

Prevention

Unilateral slanting wear of a protector which points to the wrong installation of wheels, is best of all found наощупь.


PERFORMANCE ORDER
1. Periodic check of tires will relieve you of the superfluous expenses connected with their replacement because of premature wear. On a condition of tires it is possible to receive very important information on a suspension bracket and steering condition still before serious damage will be found.
2. Wear of tires can be checked by means of the simple and inexpensive indicator of depth of a protector. When depth of a protector becomes minimum admissible the tire (or tires) replace.
3. Watch drawing of a protector of tires. The deviation of wear of a protector of tires from the normal is illustrated in pictures (see fig. A characteristic type of drawing of a protector at abnormal wear of tires). Evident signs of non-uniform wear of the protector, specified in pictures, indicate need of adjustment of corners of installation or balancing of wheels. At detection of a deviation of wear of tires from the normal it is necessary to hand over the car in a workshop or on car repair shop and to eliminate malfunction.
4. Regularly check tires, watch emergence of damages to a type of cuts or swellings, delete the stones which have got stuck in a protector or sharp subjects.
5. At a tire puncture in it a certain time will sometimes remain pressure, or small pressure decrease as the place of a puncture can be blocked by the got stuck sharp subject will be observed. If weak pressure decrease in tires is observed, check tightness of a zolotnik of the gate for a rating (the special key which is available on wide sale is for this purpose intended).
6. Check existence in a protector of the got stuck subjects which can cause a puncture.
7. If there is a suspicion that the tire is punctured, check a place of a possible puncture by means of soap solution. If the gate is tight, lift the car from the lowered wheel, and turning a wheel, обмыльте its solution.
8. In a place of a puncture the exit of bubbles will be observed. In case of leak formation of bubbles will be observed. At insignificant damage of the tire it can be repaired in shinoremontny ь a workshop or garage conditions.
9. Carefully check internal lateral surfaces of tires, watch emergence of traces of a podtekaniye of brake liquid on them, at their detection immediately check a condition of brakes.
10. Pressure maintenance in tires will allow to prolong term of their service and will increase traffic safety. Pressure in tires cannot be estimated precisely only external survey, especially it concerns radial tires. Pressure in tires is checked by a manometer. The manometer constantly should be carried with itself in a perchatochny box. Manometers at filling stations which are established on hoses of an air route, as a rule give inexact evidences.
11. Pressure is checked on cold tires. The term "cold" means that before pressure measurement in tires the car made one trip on distance in 1,5 km within three hours. On the warmed-up tires pressure can raise on 0,25–0,6 atm.
12. To prolong tire service life regularly (weekly) check pressure the checked manometer (obligatory to check pressure in a spare wheel). Unscrew a gate cap (it is located on the tire or under a wheel cap) and densely press a manometer to the gate. Consider indications of a manometer and compare with standard (see subsection 2.1).
13. Surely establish into place a cap. Check pressure in all wheels, if necessary restore pressure to norm.
