negative camber tires

The angle allows making high speed cornering a breeze. Excessive camber either way will cause excessive and abnormal tire wear. Negative camber is when the wheels are inclined towards the chassis of the car. Introducing positive (or negative) camber to an airfoil will have a profound effect on its lift curve and drag polar.

Symptoms include poor handling, a pull or drift to the side with the most positive camber, and tire and part wear. In the case of negative camber, the front wheels have an inward inclining position.

When your front wheels have a negative camber, they are inclining inward. When we use the term, we’re referring to static negative camber. Increased Suspension Wear.
