Which statement about alignment checks before new tires is correct?

The statement that alignment checks before new tires 'depends on the technician's recommendation' can be understood in context. While there are general best practices concerning alignment checks, the necessity for such a procedure can vary based on the specific vehicle condition, the type of tires being installed, and other factors like previous wear, driving habits, and the vehicle's current handling characteristics.

A technician's assessment often considers these specifics and can provide a personalized recommendation based on experience and observations during the service visit. For example, if the vehicle has exhibited signs of alignment issues like uneven tire wear or steering difficulties, a technician might strongly suggest an alignment check before new tires are installed to ensure optimal performance and longevity of the tires.

Alignment checks are not universally mandated for every tire installation situation and should be considered a case-by-case decision, hence the correctness of this answer rooted in professional judgment.
