The adjustment of which angle affects tire wear on a front tire?

The adjustment of all three angles—camber, caster, and toe—can significantly affect tire wear on a front tire.

Camber refers to the tilt of the wheels in relation to the vertical axis when viewed from the front of the vehicle. If the camber is incorrect, it can cause uneven wear on the tires. For example, excessive negative camber may result in increased wear on the inside edge of the tire, while excessive positive camber can lead to wear on the outer edge.

Caster is the angle of the steering axis, which affects the stability and handling of the vehicle. While it's more about steering characteristics, its improper adjustment can still influence how the tire contacts the road surface over time, potentially impacting tire wear, although to a lesser extent than camber or toe.

Toe refers to the direction the tires point in relation to the centerline of the vehicle. If the toe is misaligned, it can cause significant irregular tire wear. For instance, if the tires are toed in or out, they will drag against the road unevenly, resulting in faster deterioration in specific areas of the tread.

Given that each of these adjustments can contribute to uneven tire wear, selecting all of the angles as affecting front tire wear is accurate. Understanding
