What angle might cause pull without causing tire wear?

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

Answer: (C)

Caster is the tilt of the steering axis when you look at the suspension from the side. Positive caster helps the vehicle track straight and gives a self-centering feel, which improves stability and steering effort. If the left and right sides have different caster values, the steering geometry on each side behaves differently, and that imbalance can make the car pull toward one side without causing the tires to scrub or wear from contact with the road. In that sense, caster can produce a pull without the tire wear that toe or camber would cause. By contrast, camber mainly affects how the tire wears on the inner or outer edge, and toe directly scrubs the tire surface and wears tires, while kingpin inclination influences steering feel and camber change under load rather than causing a pull alone.
