Is a Wheel Alignment Necessary When Replacing All Four Tires?

[LeJohn]

During vehicle operation, factors such as bumps or undercarriage impacts can affect wheel alignment data. Additionally, significant differences in tread patterns between new and old tires can also influence alignment. Therefore, it is recommended to perform a wheel alignment after installing four new tires to prevent abnormal wear. Wheel alignment must be performed under the following conditions: When the vehicle drifts immediately to one side after briefly releasing the steering wheel while driving straight on a level road, and this drift direction remains unchanged after switching the two front wheels left and right. When the steering wheel feels loose or shaky during driving, or when it doesn't return to center automatically after turning. When abnormal uneven tire wear is observed, particularly severe wear on one side of the front or rear tires. After the vehicle's chassis or suspension system has been damaged in an accident, a wheel alignment must be performed again.
