Why does the steering wheel become misaligned after replacing rear tires?

[MicahLynn]

After replacing rear tires, the steering wheel becomes misaligned due to inaccurate four-wheel alignment data. It is recommended to perform a four-wheel alignment to resolve this issue. All four wheels of a car have alignment specifications and are not perfectly perpendicular to the ground. The front wheels have toe-in and camber angles, while the rear wheels also have camber angles. If the four-wheel alignment data is incorrect, it can cause the steering wheel to be off-center, lead to vehicle pulling, or result in uneven tire wear. Additional information about four-wheel alignment: 1. Driving over speed bumps or rough roads during normal operation may alter the four-wheel alignment data, so regular four-wheel alignments are necessary. 2. After replacing tires, wheel balancing should also be performed. If wheel balancing is not done after tire replacement, abnormal vibrations may occur during high-speed driving, which can affect the vehicle's driving stability.
