Excessive wear on the inner edge of a tire indicates which alignment issue?

Explanation:
Excessive wear on the inner edge means the tire’s contact patch is tilted toward the inside of the vehicle. That pattern points to negative camber, where the top of the wheel tilts inward. With negative camber, more tread bears load on the inner edge, so that part wears faster than the outer edge. Positive camber would wear the outer edge instead. Toe-in or toe-out changes front-to-back scrubbing and edge wear patterns differently, so they don’t produce the inner-edge wear described here. In short, negative camber causes inner-edge tire wear.
