Wheel alignment is a process that involves adjusting the angles of the wheels on a vehicle to ensure that they are set to the car manufacturer's specifications. This helps to reduce tire wear, improve fuel economy, and provide better handling and braking. During wheel alignment, technicians measure the camber, caster, and toe angles of each wheel using specialized equipment. If any of these angles are out of specification, adjustments can be made to bring them back into line. Wheel alignment is an important part of regular vehicle maintenance and should be performed every 6–12 months or whenever new tires are installed.
