Check of a condition and pressure of a rating of tires

It is extremely important to support constantly tires in good repair and symbol pumped up with due pressure - the wheel exit out of operation during movement (at any speed) is extremely dangerous. Speed of wear of protectors of tires first of all is defined by a driving manner - frequent sharp braking and accelerations, commission of turns without decrease in speed, etc. factors considerably promote reduction of service life of tires. As a rule, protectors of forward wheels wear out slightly earlier back therefore timely performance of rotation of wheels of the car allows to achieve more uniform wear of tires and, as a result, extension of term of their service. It is necessary to notice, however, that at uniform wear of protectors the owner of the car faces need 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 tires in pairs, rassosredotochivy 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 extraction of a nail the fact of a puncture of a wheel is elicited, insert a nail back into the opening punctured with it, having marked with that defect, then change a wheel and deliver failed in a shinomontazhny workshop for repair.
Pay also attention to such defects, as cracks, cuts, swellings ("egg"), etc. which are formed on a lateral surface of the tire more often. Regularly remove wheels for careful cleaning of disks of dirt as with external, and from the inside. Check rims of disks on existence 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 a hire way on the special machine which is available practically in any shinomontazhny workshop. In case of strong damages disks are not subject to restoration, and their replacement becomes the unique alternative.

Each time at replacement of tires of a wheel are subject to balancing assembled. Need for repeated balancing of wheels can arise in the course of wear of protectors, and also in a case утери counterbalances. Violation of balancing of wheels leads to reduction of service life of protectors at the expense of acceleration of their wear, besides, during movement vibrating load of suspension bracket and steering components considerably increases. The first sign of violation of balancing of wheels is emergence of the appreciable vibrations which are especially appreciable at certain speeds of movement (usually around 80 km/h [50 miles/h]). If vibration is transferred mainly to a steering wheel violation of balancing of only forward wheels, therefore, takes place. At body vibration follows отбалансировать all wheels of the car. Balancing of wheels should be made in the conditions of a shinomontazhny workshop.

Visual check of degree of wear of a protector

Entering into a standard complete set of cars of the Citroёn Xantia brand of a wheel are usually equipped with the built-in indicators of wear of protectors.

Indicators represent color strips of rubber (In), built in in an average part of a protector and being shown at wear of the last to residual depth of a pattern 1.6 mm are lower. Location of indicators on a protector is determined by the triangular labels, put a lateral surface of the tire (And).

Measurement of residual depth of a protector manually

Alternatively degree of wear of the tire can be defined by a way of measurement of residual depth of a protector by means of special щупа, to get which it is possible rather cheaply practically in any shop of automobile accessories.

Check of pressure of a rating of tires

Check of pressure of a rating of tires should be made regularly and on cold wheels. Performance of correction of pressure right after trip end when the wheel did not cool down yet, will lead only to violation of demanded parameters.

Typical examples of wear of protectors

Humeral wear

Uniform humeral wear of a protector (identical from its both parties) usually is defined by an excessive deflection of the tire as a result of too weak pressure of its rating and is accompanied by decrease in coupling with a paving and reduction of service life of a wheel, not to mention the increased danger of a rupture of the tire during movement. Check and modify pressure of a rating of tires.

Unilateral humeral wear of a protector appears is connected with violation of corners of installation of a wheel more often. It is necessary to check immediately geometrical parameters of a suspension bracket and to make the corresponding corrections.

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

Central wear

Excessive pressure of a rating of the tire leads to more dense contact to a paving of the central part of a protector that conducts to the accelerated operation of the last. Among by-effects it should be noted decrease in coupling of a wheel with a paving, increase of rigidity of a course of the car, not to mention increase of risk of an unexpected rupture of the tire. Check and modify pressure of a rating of tires.

Sometimes temporary increase of pressure in tires 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 tires to normal at return to usual service conditions of the car.

Non-uniform wear

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

At violation 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 and properly to modify balancing of wheels.

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

Scaly wear of a protector by which violation of convergence of wheels is usually accompanied, most easier is defined to the touch.
