Which statement about camber settings and tire wear is true?

• A. Positive camber increases inner-edge grip and reduces wear on the inner shoulder.
• B. Camber has no impact on wear or grip.
• C. Camber settings only affect wet conditions.
• D. Negative camber increases inner-edge grip during cornering but excessive camber wears the inner shoulder; too much camber reduces outer-edge contact and overall grip; set camber to balance wear and grip across the tire.

Answer: (D)

Camber angle determines how much tread stays flat on the road as the car leans in a turn, so grip and wear depend on how the contact patch is loaded. Negative camber tilts the top of the tire inward, which helps keep more tread in contact during cornering and boosts inner-edge grip. But if camber is too negative, the inner shoulder wears quickly because it remains loaded, while the outer edge loses contact and overall grip can drop. The idea is to set camber to balance wear across the tire and maintain stable grip through corners and on the straights. Positive camber would push more load to the outer edge and reduce inner-edge grip, which isn’t helpful for balancing wear and grip; camber effects are relevant in dry and wet conditions alike.
