Answer
An overinflated tyre causes excessive wear in the middle of the tyre. This occurs because the increased pressure forces the tyre's center to make greater contact with the road, leading to a rapid reduction in tread depth in that area.

Answer
Negative camber results in excessive wear on the inside edge or shoulder of the tyre. This is due to the fact that the wheels are tilted inward, causing more load and friction on the inner tread during cornering.

Answer
The purpose of toe-in is to counteract the tendency of the wheels to move outward due to positive camber. This alignment helps ensure that the vehicle tracks straight on the road, improving stability and handling.

Answer
Negative caster allows for easier turning of the steering wheel. It creates a setup where the kingpin inclination assists in steering response, making maneuvering simpler, especially at low speeds.
