How Does Tire Alignment Work in a Vehicle?
Tire alignment works by adjusting the angles of a vehicle’s wheels. Proper alignment ensures that the tires make contact with the road in the correct way. This process involves three main angles: camber, caster, and toe.
Camber is the inward or outward tilt of the tire when viewed from the front. Positive camber means the top of the tire tilts outward, while negative camber tilts inward. Caster refers to the angle of the steering axis when viewed from the side. A positive caster angle helps with stability and steering. Toe refers to the direction the tires point relative to the centerline of the vehicle. If the front of the tires points inward, it’s called toe-in; if they point outward, it’s called toe-out.
To perform an alignment, a technician uses specialized equipment to measure these angles. They compare the measurements against the manufacturer’s specifications. If the angles are outside the specified range, adjustments are made. For camber, the technician alters the top of the wheel assembly. For caster, they adjust the position of the control arms. For toe, the technician adjusts the tie rods that connect the steering system to the wheels.
Proper tire alignment offers several benefits. It improves tire lifespan, enhances fuel efficiency, and ensures better handling. Misalignment can cause uneven tire wear and affects the vehicle’s steering. Regular checking of alignment is essential, especially after hitting a pothole or curb.
