Is a wheel alignment necessary after replacing all four tires?

[Isaac]

Replacing all four tires does not require a wheel alignment because normal tire and wheel replacement does not affect the chassis data. Therefore, a wheel alignment is unnecessary. However, if the tires are replaced due to severe abnormal wear, which has impacted the chassis data, then a wheel alignment is needed. Wheel alignment equipment includes toe gauges, optical level aligners, string aligners, CCD aligners, laser aligners, and 3D imaging aligners, among others. Among these, 3D, CCD, and laser products are the mainstream in the market. Tires are typically made of wear-resistant rubber materials and can be either solid or pneumatic. Pneumatic tires consist of an inner tube and an outer tire. Generally, manufacturers set the service life of tires at 3 years. If a vehicle is driven 20,000 kilometers per year, replacement may be considered after 2 to 3 years.
