Additionally, the National Highway Traffic Safety Administration emphasizes the importance of wheel alignment for safe driving and to maximize tire life.
The underlying causes for the need for alignment after tire size changes stem from geometric variations. Larger or smaller tires can change the distance from the center of the wheel to the road, altering the camber, caster, and toe angles. Camber refers to the tilt of the wheels, caster refers to the angle of the steering axis, and toe refers to the direction the tires point relative to the centerline of the vehicle. These changes can lead to poor handling characteristics and uneven tire wear.
The technical term “camber” describes how far the tops of the tires lean inward or outward. A positive camber angle means the tops lean outward, while a negative camber angle means they lean inward. When you change tire sizes, these angles can become misaligned, resulting in diminished performance and safety.
Mechanisms involved in alignment include the ability of the suspension system to position the tires correctly. Components like control arms, struts, and shocks play a role in maintaining the correct angles. Changes in ride height, which can occur with different tire sizes, affect these angles and can result in misalignment.
Specific conditions contributing to alignment issues include the change in tire diameter or width. For example, moving from a standard tire size to a larger diameter can increase the distance to the wheel arch, affecting the vehicle’s overall geometry. Similarly, switching from a low-profile tire to a higher profile tire can alter the suspension dynamics and lead to significant misalignment.
In summary, proper alignment after changing tire size is crucial for maintaining vehicle performance and safety. It ensures that the tires wear evenly and that the vehicle handles as designed.
