Answer
An overinflated tyre often shows excessive wear in the middle section of the tread. This occurs because the increased pressure pushes the tyre's center further down onto the road, resulting in less contact from the edges.

Answer
Negative camber typically results in excessive wear on the inside edge of the tyre. This is due to the tilt of the wheels, causing the inside edge to make more contact with the road during driving.

Answer
Toe-in is used to counteract the natural tendency of wheels to move outward due to wear and driving forces. By slightly angling the front of the wheels towards each other, it helps improve stability and steering responsiveness.

Answer
Negative caster helps ensure easier turning of the vehicle. This angle allows the front wheels to pivot more freely, enhancing the vehicle's maneuverability, particularly while steering.
