Diagnostics of vibrations

The imbalance of wheels is the main reason for vibrations on high speed. If after balancing of wheels of vibration remained, it can be caused by one of three reasons:

  • Wear of a tire.
  • Wear of a disk.
  • Unevenness of rigidity of a tire.

Check of wear of tires and disks can reveal only a part of a problem. All three reasons causing radial palpation, can be checked by means of the detector of defects of tires (TPD). If TPD is inaccessible, there is other, longer method of shift of others, obviously qualitative, wheels on the car.

[A] — it is caused by change of a form of a tire
[B] — it is caused by unevenness of rigidity of a tire
[C] — change of a form of a disk is caused
1 — the equal road
2 — suspension bracket moving
