What is the primary purpose of wheel alignment?

The primary purpose of wheel alignment is to ensure that the wheels are set to the optimal angle for even tire wear and stable handling. Proper alignment affects how the vehicle handles and rides, as well as how tires wear over time. When the wheels are not aligned correctly, it can lead to uneven tire wear, which means the tires may need to be replaced sooner than expected, increasing costs for the vehicle owner. Additionally, improper alignment can result in poor handling and stability, making the vehicle more difficult to control.

Other options may relate to vehicle performance but do not encompass the primary function of wheel alignment. While enhancing fuel efficiency can be a secondary benefit of proper alignment due to reduced rolling resistance, it is not the main goal. Adjusting the clearances between suspension components is a different aspect of suspension maintenance, and improving engine performance does not directly connect to wheel alignment. The focus is clearly on ensuring optimal angles for wheel placement, which directly contributes to tire longevity and vehicle control.
