What potential issue arises from camber that is too positive or too negative?

When camber is either too positive or too negative, the primary issue that arises is increased tire wear. Camber refers to the angle of the wheels in relation to the vertical axis when viewed from the front of the vehicle.

Positive camber means that the tops of the wheels are angled outward, away from the vehicle, while negative camber means the tops of the wheels are tilted inward, towards the vehicle. Both scenarios can lead to uneven tire contact with the road surface, causing certain parts of the tire tread to bear more load than others. This uneven distribution of weight can result in accelerated wear on the tires, leading to a decrease in their lifespan, reduced traction, and potential handling issues as the tires begin to lose their effectiveness.

In contrast, other potential issues such as increased fuel consumption or improved handling are not directly tied to camber angles. While excessive camber may affect ride comfort or handling characteristics negatively, the most immediate and tangible consequence of incorrect camber alignment is indeed the increased wear on tires.
