Is it necessary to perform a four-wheel alignment when changing tires?

[McCassandra]

Tires are replaced due to normal wear reaching the wear indicators or damage. After replacing tires, a four-wheel alignment is not necessary because normal tire and wheel replacement does not affect the chassis data. However, if the tires are replaced due to severe abnormal wear, which impacts the chassis data, then a four-wheel alignment is required. Performing a four-wheel alignment involves adjusting numerous parameters, including camber, caster, toe angle, and kingpin inclination angle. This process not only tests the technician's professional skills but also heavily relies on the quality of the equipment used.
