Check of a condition of tyres and pressure of their rating, rotation of wheels
Regular check of a condition of tyres will allow to avoid the troubles connected with stops in a way because of the lowered wheel. Besides, such checks give the valuable information on possible problems with components of a steering drive and a suspension bracket till the moment of occurrence of occurrence in them of serious damages.
At a sports manner of driving it is recommended to increase pressure in forward and back tyres on 0.2 атм, an outcome from base-line values.
Tyres can be equipped by the built in indicators of deterioration of a protector in the form of the colour strips bared at decrease of depth of a protector to 1.6 mm, - the given value is minimum admissible, in most cases it is recommended to replace the tyres which depth of a protector makes less than 2 mm. Depth of a protector always can be defined by means of the simple and inexpensive adaptation known under the name of a measuring instrument of depth of a protector.
Pay attention to signs of non-uniform deterioration of protectors. Such defects as cavities, swellings, уплощения and unilateral deterioration specify in infringement of corners of installation of wheels, or on disbalance of wheel assemblage, - drive away the car on station of adjustment of disorder-convergence.
Carefully check tyres on presence of cuts, punctures and got stuck nails or buttons. Sometimes after a puncture of the tyre a nail it still some time holds pressure, or starts to pit air very slowly. At suspicion on presence such «a slow puncture» first of all it is necessary to check up tightness of a nipple of a rating of a wheel, then attentively to examine a protector on presence at it got stuck strangers of subjects, and also eliminated earlier and again allowed to "flow" damages. To make sure available a puncture it is possible, having moistened a suspected site with soap water, - an air outlet sign becomes it пузырение. If not too big, the tyre it is usually possible to restore a puncture in any шиномонтажной a workshop.
Carefully examine internal lateral surfaces of tyres on presence on them of signs of development of leaks of a brake liquid, - if those are available, immediately check up a condition of brake mechanisms.
Remember that maintenance in tyres of correct pressure increases term of their service, helps to save fuel and improves the general comfort of movement. The special manometre is necessary for pressure check.
Always check pressure upon cold tyres, otherwise the result of measurement will be overestimated owing to thermal expansion of air.
For check of pressure of a rating of the tyre remove a protective cap from a nipple, then densely press to the gate of a rating a nozzle of a manometre and consider instrument readings. Compare results of measurement to requirements of Specifications of the Head Current leaving and service. Do not forget to plant into place the protective cap preventing hit in a nipple of a dirt and a moisture. Check pressure in all tyres, including a spare wheel. In case of need make corresponding updatings.
It is not necessary to trust indications of the manometres connected to pump stations at the gas station.
Examples of characteristic deterioration of protectors of tyres
Insufficient pressure in the tyre leads to its overheat at movement owing to an excessive deflection therefore the protector does not nestle sufficiently on a road surface. It leads to loss of coupling with road and to excessive deterioration of a protector, not to mention danger of an exit of the tyre out of operation as a result of an overheat. Check up and adjust pressure.
Infringement of adjustment of disorder of wheels also can lead to unilateral deterioration of a protector, - replace defective components of a suspension bracket / a steering drive, execute disorder adjustment.
One more reason of such deterioration too sharp fulfilment of turns can be, - change a driving manner.
The central deterioration
Superfluous pressure in the tyre leads to the accelerated deterioration of the central part of a protector, decrease in coupling with road, to more rigid movement and increase of danger of fatal damage of a slope, - check up and adjust pressure. If tyres have been pumped up for transportation of heavy cargoes, do not forget at return to a normal mode of operation to pit superfluous air.
Tyres of forward wheels can non-uniformly wear out as a result of infringement of corners of installation of wheels, - check up, replace defective components of a suspension bracket / a steering drive, make necessary updating.
One more this sort of reason of deterioration infringement of balancing of wheels can be, - drive away the car in шиномонтажную a workshop.
Edges Obtrepannost of a pattern of the protector, being a deterioration sign, is better comes to light to the touch.
Rotation of wheels
||Rotation of wheels it is necessary to make each 12 000 km (7500 miles) run. At rotation of wheels do not forget to check a condition of tyres and if necessary to replace them.
