Wheel alignment

Here we are with one interesting lesson by our engineers about the wheel alignment.

What's the wheel alignment?


The angle between the wheel and the vehicle's axis, or the difference between the front borders and the back borders of the axis that is measures in the center.

Why do we need to take care of the wheel alignment?


The correct wheel alignment is part of the standard automobile maintenance and improves driving, the usage of wheels as well as the rolling.


Wheel alignment = 0


When the wheel alignment is zero the distance between front and back borders of axis wheels are the same.

Positive wheel alignment (+)


The distance between front borders of wheels and their axis is lower than the distance between the back borders.
An extreme wheel alignment causes:

  • instability of the vehicle
  • rapid usage of the border of the wheels
    •  the wrong usage ruins the border with peculiar signs (saw tooth shape or lines)
    • you can find out a positive wheel alignment by touching the tire tread inside out
  • • major fuel consumption 



Negative wheel alignment (-)


The distance between the front borders is more than the distance between the back borders.
An extreme wheel alignment causes:

  • instability of the vehicle
  • rapid usage inner wheel's border
    • the wrong usage ruins the border with peculiar signs (saw tooth shape or lines)
    • you can find out a negative wheel alignment by touching the tire tread inside out
  • major fuel consumption
