Caster is the tilting of the uppermost point of the steering axis either forward or backward when viewed from the side of the vehicle. A backward tilt is positive; a forward tilt is negative. Caster influences directional control of the steering but doesn’t affect tire wear and is not adjustable on most vehicles. Caster is affected by vehicle height, so it is important to keep the body at its designed height. An overloaded vehicle or one with a weak or sagging rear spring will affect the caster.


Camber is the tilting of the wheels from the vertical when viewed from the front of the vehicle. When wheels tilt outward at the top, the camber is positive; when wheels tilt inward at the top, the camber is negative. The amount of tilt is measured in degrees from the vertical. Camber settings influence directional control and tire wear. Too much positive camber will result in premature wear on the outside of the tire and excessive wear on the suspension parts. Too much negative camber will result in premature wear on the inside of the tire as well as excessive wear on the suspension parts.


Toe is a measurement of how much the wheels are turned in or out from a straight-ahead position. When the wheels are turned in, toe is positive; when the wheels are turned out, toe is negative. The actual amount of toe is normally only a fraction of a degree. The purpose of toe is to ensure that the wheels roll parallel. Toe also serves to offset the small deflections of the wheel support system that occurs when the vehicle is rolling forward. In other words, with the vehicle standing still and the wheels set with toe-in, the wheels tend to roll parallel on the road when the vehicle is moving. Improper toe adjustment will cause premature tire wear and steering instability.

When you bring your vehicle into Pfaff Tuning for a wheel alignment, your technicians will take a look at its caster, camber, and toe. The technician will then make their adjustments based on their findings.
