Is a Four-Wheel Alignment Necessary When Replacing Two Tires?
1 Answers
Generally, replacing tires does not require a four-wheel alignment, but tire dynamic balancing is definitely needed after tire replacement. A four-wheel alignment is typically performed when the vehicle exhibits issues such as deviation while driving, misaligned steering wheel, or abnormal tire wear. Problems like tire cupping or scalloping occur due to incorrect four-wheel alignment data, necessitating a four-wheel alignment. Below are detailed explanations about four-wheel alignment: Reasons for Four-Wheel Alignment: Because there are certain angles and relative positions between the car tires, steering mechanism, and front and rear axles, these angles and positions may shift after tire replacement. This can lead to issues such as vehicle deviation, reduced steering precision, misaligned steering wheel, and tire cupping, requiring timely four-wheel alignment. Purpose of Four-Wheel Alignment: It ensures that the tires maintain the optimal angle with the vehicle body, reduces wear between the tires and steering components during driving, guarantees tight contact between the tires and the ground, and helps the car maintain stable straight-line driving. Notes on Tire Repair: Tire repair does not require a four-wheel alignment; only dynamic balancing is needed. Performing a four-wheel alignment after tire repair can easily disrupt the balance of the vehicle's suspension.
