What is the primary purpose of adjusting camber in a wheel alignment?

The primary purpose of adjusting camber in a wheel alignment revolves around ensuring that the tires maintain optimal contact with the road surface. Camber refers to the angle of the wheels in relation to the vertical axis of the vehicle. When the camber is set correctly, the tire's contact patch (the part of the tire that makes contact with the road) maximizes, which leads to better grip and stability while driving.

Proper camber adjustment allows for even tire wear and improves handling dynamics, enhancing the vehicle's overall performance. If camber is out of specification, it can lead to uneven tire wear and can negatively impact steering stability and cornering ability. Thus, by focusing on the camber angle adjustment, technicians can help ensure the vehicle's tires effectively engage with the road, providing better traction, control, and safety.

While the other options may relate to vehicle performance in various ways, camber's direct influence on maintaining adequate tire contact with the road makes it the most relevant factor in this context.
