Repair and car operation

Check of a condition and pressure of a rating of tyres

Extremely important constantly to support tyres in good repair and pumped up with due pressure symbol - a wheel exit out of operation during movement (at any speed) it is extremely dangerous. Speed of deterioration of protectors of tyres first of all is defined by a driving manner - frequent sharp braking and accelerations, fulfilment of turns without decrease in speed, etc. factors appreciably promote reduction of service life of tyres. As a rule, protectors of forward wheels wear out a little before back, therefore timely performance of rotation of wheels of the car allows to achieve more uniform deterioration of tyres and, as consequence, prolongation of term of their service. It is necessary to notice, however, that at uniform deterioration of protectors the owner of the car faces necessity of performance of single replacement at once four wheels, what not each motorist can appear on a pocket. In this case it is better to neglect rotation of wheels and to make replacement of tyres in pairs, рассосредоточивая thereby material inputs.

Regularly examine protectors of all wheels of the car, taking from profile flutes of a protector the small stones which have got stuck in them, nails and other extraneous subjects before they will cause a wheel puncture. If at nail extraction the fact of a puncture of a wheel is elicited, insert a nail back into the aperture pierced by it, having marked with that defect, then change a wheel and deliver failed in шиномонтажную a workshop for repair.
Pay also attention to such defects, as cracks, cuts, swellings ("egg"), etc. which are formed on a lateral surface of the tyre more often. Regularly remove wheels for careful clearing of disks of a dirt as with external, and from the inside. Check rims of disks on presence of traces of development of corrosion, deformations and other damages. Remember that the disks made of an easy alloy easily fail at arrivals on поребрики and deep defects of a covering. Stamped disks in such situations usually are only deformed and can be restored by hire on the special machine tool which is available practically in any шиномонтажной by a workshop. In case of strong damages disks are not subject to restoration, and their replacement becomes unique alternative.

Each time at replacement of tyres of a wheel are subject to balancing in gathering. Necessity for repeated balancing of wheels can arise in the course of deterioration of protectors, and also in a case утери counterbalances. Infringement of balancing of wheels leads to reduction of service life of protectors at the expense of acceleration of their deterioration, besides, during movement vibrating loading on suspension bracket and steering components appreciably increases. First sign of infringement of balancing of wheels is occurrence of the appreciable vibrations especially appreciable at certain speeds of movement (usually around 80 km/h [50 miles/ch]). If vibration is transferred mainly to a steering wheel infringement of balancing of only forward wheels, hence, takes place. At кузовной to vibration follows отбалансировать all wheels of the car. Balancing of wheels should be made in conditions шиномонтажной by a workshop.

Visual check of degree of deterioration of a protector

Entering into a standard complete set of cars of mark Citroёn Xantia of a wheel are usually equipped by the built in indicators of deterioration of protectors.

Check of pressure of a rating of tyres

Typical examples of deterioration of protectors

Humeral deterioration

Uniform humeral deterioration of a protector (identical from its both parties) is usually defined by an excessive deflection of the tyre as a result of too weak pressure of its rating and accompanied by decrease in coupling with a road covering and reduction of service life of a wheel, not to mention the raised danger of rupture of the tyre during movement. Check up and modify pressure of a rating of tyres.

Unilateral humeral deterioration of a protector appears is connected with infringement of corners of installation of a wheel more often. It is necessary to check up immediately geometrical parametres of a suspension bracket and to make corresponding corrections.

One more of the reasons of humeral deterioration of a protector is too sharp manner of driving - reduce speed on turns!

The central deterioration

Excessive pressure of a rating of the tyre leads to more dense contact to a road covering of the central part of a protector that conducts to the accelerated operation of last. Among by-effects it is necessary to note decrease in coupling of a wheel with a road covering, increase of rigidity of a course of the car, not to mention increase of risk of unexpected rupture of the tyre. Check up and modify pressure of a rating of tyres.

Sometimes time increase of pressure in tyres appears necessary as, for example, in cases of transportation of heavy cargoes, at long driving with high speeds, etc. do not forget to dump pressure in tyres to normal at returning to usual service conditions of the car.

Non-uniform deterioration

Non-uniform deterioration of protectors of tyres of forward wheels can be connected with infringement of corners of installation of the last. To check up and modify geometry of a forward suspension bracket of the car for rather small payment it is possible practically in any шиномонтажной for a workshop.

At infringement of disorder or выбега wheels it is necessary to make necessary repair or replacement of the failed components of a suspension bracket.

Do not forget to check up and properly to modify balancing of wheels.

At infringement of convergence of wheels it is necessary to make corresponding adjustments also.
