. Cross-section of the radial tire: 1–protector block; 2–protector flute; 3–protector; 4–nylon bandage; 5–cord layers; 6–board core; 7–amplifier of a board; 8–protection onboard закраины

Nylon bandage 4, layers of a cord 5, cores of a board 6 and amplifiers of a board 7 base a framework. The framework is «a bearing element» tires.
Damages from blows
Camber in боковине indicates tires framework damage.

Fig. 4.21
. Arrival on a border at an acute angle
|
Typical "responsible" for similar damages are, for example, borders at arrival on them at an acute angle
(fig. 4.21)
.
Because of it the framework of the so strongly compressed tire can be damaged.
The tire framework thus is strongly stretched that leads to a rupture of separate fibers.
The scale of damage depends on speed and a corner of blow, pressure of air in tires, loads of an axis and a type of an obstacle.

NOTE
Arrival on borders should be avoided.
If to drive on a border after all it is necessary, through its edge it is necessary to move at an obtuse angle and very slowly.

|
Because of strong blow the framework was jammed at onboard закраины and
(fig. 4.23) became torn in a contact point
.
Internal damage of the tire because of blow (a double gap)
The double gap which has resulted compression at arrival on a border, is often imperceptible outside
(fig. 4.24)
