It also affects the directional stability of the vehicle and tends to unevenly wear out the opposite side tire. Excessive camber causes the tires to have incorrect contact with the road.
It causes them to wear on the side directly under the load. In modern vehicles, manufacturers provide either an eccentric cam in the control arm shaft or shims to adjust the camber. Hence, it is important to carry out the wheel-alignment regularly which includes adjusting camber to manufacturer's specifications.
They slant inwards as seen from the front of the vehicle. The center-line of kingpin or ball joints forms an angle with the vertical axis. It is known as the kingpin inclination or the steering axis inclination. Because the kingpin or ball-joints forms a pivot around which the steering knuckles rotate when you turn the wheels. They slant inwards and raise the weight of the vehicle when the wheels are in any position except straight ahead.
In this way, the weight of the vehicle helps to keep the front wheels pointed forward. In fact, NASCAR drivers always turn left driving a counter-clockwise loop , so their cars have negative camber on the right wheels and positive camber on the left wheels.
This is terrible for driving straight but perfect for their type of racing! Negative camber increases the tire wear under normal driving conditions, usually with mostly straight driving. However, performance drivers do not need to replace their performance tires as often when doing a lot of cornering since negative camber decreases the relative tire wear under these conditions.

Bushings and other components of the suspension may experience increased wear with negative camber because of how forces act on these parts. Camber is best measured by a professional with specialized equipment, such as an alignment rack.
It can also be measured albeit less accurately with a bubble level and a camber gauge. Before measuring, the joints in the suspension should be checked to ensure they are within spec as that can throw off the measurements. Inappropriate camber for the vehicle and its use can result in excessive tire wear, poor stability, or other handling issues.
Performance drivers adjusting camber on their vehicles often also want to know how the contact patch changes. This is measured by a pyrometer, also known as a non-contact infrared thermometer. The contact patch in the turn will be hotter due to friction. The way the camber is adjusted depends on the type of suspension.
Because of the way the wheels would be angled, both sides are pushing against each other. This certainly helps with handling when both are in contact with the road, but the moment one of them loses traction, the car will involuntarily thrust towards its direction. Negative camber has its benefits, but only when the wheels are properly tilted. Because of the dangers involved in having too much negative camber, if you want to have it done on your vehicle, be sure to get someone who is well-experienced in such jobs.

The importance of the camber angle has to do with how stable it makes the vehicle on the road, particularly when making turns around corners. The general consensus is that a positive camber is good for keeping a recreational vehicle stable, while a negative camber is better for allowing high-performance vehicles to turn corners faster and more accurately.
You use degrees to measure the camber angle when figuring out the distance that the wheels will incline from the vertical axis. See Also: What is Caster? Positive and Negative Effects.
