NOTE
To repair radial tires with the steel cord, having framework damage by an extraneous subject, it is not recommended.
There can be a corrosion on a steel wire. It leads to a rubber otsloyeniye from a steel cord.

As a rule, to find out, when arrival on an extraneous subject was made, it is impossible. Damage of a framework of the tire because of driving with insufficient pressure in the tire as a result can take place.
Damage leads sooner or later a cord provolok to a rubber otsloyeniye from a steel cord. In a consequence of it after a while, much later, than there was an initial damage, there can be a nonrestorable damage of the tire.

Pressure of air in the tire
Pressure of air in tires is necessary for checking regularly. It is recommended to supervise pressure in tires with periodicity of 14 days. It is necessary to give special attention to this question at trips on long distances or at load of the car. Sports style of driving also demands the correct pressure in tires or even the slightly bigger.

Slow spuskany tires
Slow spuskany tires is very artful phenomenon as even skilled drivers often do not notice it.
Because of insufficient pressure of air in the tire and the related bigger work of lateral deformation (an internal friction) materials of the tire heat up so strongly that the otslaivaniye of various elements of a framework and rubber mixes is not excluded.
Final stage is completely destroyed tire more often.
The reason of a slow spuskaniye of the tire not always manages to be found out, as as a result the tire appears strongly damaged, and quite often there are no framework elements.

Growth of temperature of the tire at insufficient pressure

Fig. 4.25 . Change of temperature of the tire at speed of 180 km/h


The schedule shows change of temperature of the tire at speed of 180 km/h (fig. 4.25) .
A–Normal range. Bei Einhalten des vorgeschriebenen Luftdrucks bleibt die Temperatur im Gleichgewicht.
B–Dangerous zone. At shortage of pressure of air a bar the temperature increases in the tire 0,3 of over 120 °C at high speeds.
C–Critical temperature. Tire damage begins.
T–Temperature in °C.
t–Driving time in minutes.
