The ___ angle is the inward or outward tilt of the tire measured at the top.

• A. Toe
• B. Caster
• C. Kingpin angle
• D. Camber

Answer: (D)

Camber angle is the tilt of the wheel at the top inward or outward relative to the vehicle’s vertical axis when viewed from the front. This tilt determines how much of the tire’s tread is in contact with the road as the suspension moves. If the top of the tire tilts toward the vehicle, that’s negative camber; if it tilts away from the vehicle, that’s positive camber. This is different from toe, which concerns the front or rear alignment of the wheels when seen from above; it's also different from caster—the side-view tilt of the steering axis that affects steering feel—and from kingpin angle, which relates to older suspension geometry. So the description fits camber.
