Define "toe angle" in relation to wheel alignment.

Toe angle is a critical parameter in wheel alignment that refers to the angle at which the tires are positioned relative to the centerline of the vehicle, specifically indicating whether the front tires point inward or outward when viewed from above. When the front of the tires angles towards each other, it is referred to as "toe-in," whereas if the front of the tires angles away from each other, it is described as "toe-out." Proper toe alignment is essential for maintaining correct handling characteristics, tire wear, and overall vehicle stability. Misalignment can lead to uneven tire wear and affect the vehicle's steering response, highlighting the importance of this measurement in wheel alignment practices.
