Konusnost
The Konusnost is caused by small shift of a protector and/or a breker in relation to the geometrical middle of the tire on some tenth millimeter. The Konusnost visually is not appreciable and is not measured in repair truck conditions.
Because of shift rigidity on an internal and external shoulder of the tire different that results in various forces. operating on a basic surface of a wheel. Therefore a breker and a protector "rest" against a road cloth with different effort (F1, F2). The cone as a result turns out. The effort (Fk) caused by a konusnost can become so big depending on speed that will start to withdraw the car in any party.

Fig. 4.18 . Tire elements: 1–board; 2–shoulder; 3–protector; 4–metallokordny breker; a–geometrical middle of the tire; b–actual position of a breker; it can be displaced inside or outside



Fig. 4.19 . The forces influencing the tire: 1–shift брекера / protector; F1 – the unequal forces operating on a basic surface of a wheel; F2 – the unequal forces operating on a basic surface of a wheel; Fk – the force created by a konusnost


If force (Fk) on one wheel of an axis makes, for example, 50 N, on other wheel also 50 N, and these forces also are sent to the identical party, they are summarized. Thanks to a tire perevorachivaniye on a disk it is possible to compensate lateral withdrawal, as forces will operate in that case to the opposite side.
As on the tire the direction in which the force caused by a konusnost operates, not considerably to define, what tire caused lateral withdrawal, it is possible only trial trips and purposeful shift of disks and tires.
The tire consists of many elements and materials which productions at the end of labor-intensive process from a part are vulcanized. Because of it various errors which can become appreciable at more or less high lateral efforts turn out. These efforts can be shown as well on new tires.

Unilateral withdrawal on a forward axis
The reasons of lateral withdrawal can be covered in a running gear. However, by experience it is known that in over 90 % of complaints lateral withdrawal is caused by tires.

Lateral withdrawal at normal style of driving
The car "pulls" in any party on the direct, equal road, at smooth movement or moderate acceleration. Thus on a wheel the effort is felt.

Lateral withdrawal at strong acceleration
Lateral withdrawal at strong acceleration from a part is put in a design of cars with a forward drive. Various conditions of a friction of the left and right wheel, including roughness of a paving (hollow). and in this regard and changeable coupling with darling strongly influence road performance. This problem is not a guarantee case.
