What is the main purpose of wheel alignment?

The main purpose of wheel alignment is to ensure that the wheels are parallel to each other and perpendicular to the road surface, allowing them to point in the correct direction. Proper alignment is crucial for safe handling and steering of the vehicle. When the wheels are aligned correctly, it improves the vehicle's stability and responsiveness, which is essential for maintaining control during driving. This alignment also minimizes uneven tire wear, enhancing the overall safety of the vehicle. While benefits such as increased fuel efficiency and extended tire lifespan may occur as a result of proper alignment, the fundamental aim is to enhance the vehicle's handling characteristics, ensuring that it drives straight and true.
