Many owners confuse alignment and balancing.
Tire balancing fixes weight imbalance. Symptoms: steering wheel vibration at high speed. It is required after tire repair, replacement or wheel change.
Wheel alignment adjusts wheel angles. Symptoms: pulling to one side, crooked steering wheel, uneven tire wear. It is needed after hitting curbs, potholes or suspension repair.
Under normal driving, you may not need alignment for years. Too-frequent or inaccurate alignment can make handling worse.
Simple rule:

Shaking wheel → balance

Pulling or uneven wear → alignment
