Which condition might be indicated by steering wheel vibration during driving?

Steering wheel vibration during driving is often a result of unbalanced tires. When tires are not properly balanced, it leads to uneven distribution of weight as the vehicle moves. This imbalance causes the tires to vibrate at certain speeds, which is then transmitted to the steering wheel, creating noticeable vibrations. Addressing tire balance through proper alignment and balancing weights is crucial for smooth vehicle operation and steering comfort.

In contrast, while faulty anti-lock brakes, a defective power steering pump, and worn wheel bearings can lead to other symptoms, they do not typically cause steering wheel vibrations under normal driving conditions. Anti-lock brake issues may result in different sensations, such as pulsing during braking. A defective power steering pump would likely produce difficulty in steering rather than vibration. Worn wheel bearings could contribute to noise or handling issues but are less commonly associated with vibration felt primarily through the steering wheel at speed, making unbalanced tires the most logical cause for that symptom.
