Is a Wheel Alignment Necessary After Rotating Front and Rear Tires?

[AnnieLynn]

No, a wheel alignment is not necessary after rotating front and rear tires. The primary purpose of tire rotation is to ensure even wear across all four tires, thereby extending their service life. Generally, a wheel alignment is only required under the following circumstances: 1. Severe wear on one side of the tire; 2. Damage to the chassis and suspension caused by an accident; 3. After replacing steering system components; 4. The vehicle pulls to the left or right when driving straight. Wheel alignment is based on the four-wheel parameters of the vehicle, adjusting them to ensure optimal driving performance and reliability. This is because the installation of the vehicle's four wheels, steering mechanism, and front and rear axles must maintain specific relative positions, which are set by the manufacturer. The process of adjusting and restoring these standard positions is what constitutes a wheel alignment.
