Do I need a four-wheel alignment when changing tires on a sedan?

[DelLogan]

Changing tires on a sedan does not require a four-wheel alignment. After replacing tires, wheel dynamic balancing is necessary, which is unrelated to four-wheel alignment. If the vehicle does not exhibit any deviation while driving and the steering wheel remains straight, alignment is not required. However, wheel dynamic balancing is essential; otherwise, vibration may occur during driving. Four-wheel alignment is based on the vehicle's four-wheel parameters, adjusted to ensure optimal driving performance and reliability. When experiencing issues such as heavy steering, shaking, deviation, misalignment, failure to return to center, or abnormal tire wear (including uneven wear, scalloped wear, block wear, or biased wear), or when the driver feels floating, bumping, or swaying sensations, it is advisable to check the wheel alignment values to determine if significant deviation exists and proceed with timely repairs.
