Alignment sets wheel geometry; balancing corrects rotating mass. They solve different problems and should not be sold as interchangeable fixes.
What to check
Edge wear, pulling or an off-centre steering wheel can justify geometry checks.
Speed-related vibration can justify wheel/tyre balance inspection, although other faults are possible.
Ask for the cause and measurements rather than automatically authorising both services.
Choose the service that matches the symptom
Alignment changes geometry; balancing corrects rotating mass. Edge wear and an off-centre steering wheel often point toward geometry checks, while speed-related vibration can justify balance inspection. Either symptom can also have other causes.
Ask for evidence
For alignment, ask for measured angles before and after adjustment. For vibration, ask what was inspected besides balance, including tyre condition, wheel damage and suspension.
TyreDeck can help you spot warning signs, but it cannot inspect the tyre internally, measure damage, verify pressure calibration or certify that a tyre is safe to drive on. If you are unsure, avoid unnecessary driving and arrange a competent physical inspection.
What to do next
Uneven wear is worth diagnosing before simply replacing the tyre.
