What is the difference between static and dynamic wheel alignment?

The distinction between static and dynamic wheel alignment is crucial for understanding how vehicle handling and tire wear are affected by alignment settings. Static alignment refers to adjustments made when the vehicle is parked and at rest, which typically involves measuring the angles of the wheels, such as camber, caster, and toe, while the car is not in motion. This type of alignment helps ensure that the wheels are positioned correctly relative to one another and the road surface, providing a good foundation for straight-line tracking and even tire wear.

Dynamic alignment, on the other hand, is assessed while the vehicle is in motion. This allows for adjustments that take into account how the vehicle's suspension and steering systems behave under load and during driving conditions. During dynamic alignment, factors such as the vehicle's speed, load, and the effects of suspension travel are considered, which can lead to more accurate adjustments for optimal performance when the vehicle is actually on the road.

This understanding is integral to achieving and maintaining the vehicle's steering performance, tire longevity, and overall drivability.
