Optimum driving performance and minimal tire wear are only achieved when the vehicle's front wheels are correctly positioned. With increased and uneven tire wear and deterioration in handling, i.e. in case of poor straight-line stability and poor cornering control, it is necessary to contact the workshop to measure the wheel alignment using optical methods.
Angle measurements are not possible without special equipment. In this regard, this chapter describes only the basic concepts and values of the front wheel alignment angles.
