What does camber refer to in a vehicle's wheel alignment?

Camber refers to the angle of the wheel in relation to the road surface when viewed from the front of the vehicle. It is measured in degrees and can be positive, negative, or neutral. Positive camber means the top of the wheel is tilted away from the vehicle, while negative camber means it is tilted towards the vehicle. This angle affects how the vehicle handles during cornering and contributes to tire wear and stability. Proper camber alignment is crucial for maximizing tire performance and ensuring safe driving conditions.

Understanding camber is essential for achieving optimal vehicle performance, as it directly influences how the tires grip the road and the overall handling characteristics of the vehicle. The other choices describe different aspects unrelated to wheel alignment angles, such as tire diameter, suspension geometry, or shock absorber characteristics, and thus do not pertain to the definition of camber.
