Incorrect tire pressure is a common but overlooked cause of steering wheel vibrations. Underinflated tires place excessive weight on the outer tread edges, while overinflated tires crown the tread, reducing road contact. Both conditions disrupt balance and steering control, especially when front tires have uneven pressure. This imbalance can lead to mild vibrations or pronounced steering issues.

To fix this, check your vehicle’s recommended tire pressure, typically listed in the owner’s manual or on the driver’s side door frame. For a precise adjustment, use the "chalk test." Mark a chalk line across the tread, drive a short distance, and examine the wear pattern. Adjust pressure until the wear is even across the tire. Regularly checking and maintaining proper tire inflation can significantly reduce steering vibrations.

Uneven tire wear is another major culprit behind steering wheel shakes. Over time, front tires often wear faster due to their role in steering and braking. This unevenness can cause imbalances that translate into vibrations at the steering wheel.

Rotating your tires every 5,000–7,500 miles (or roughly every other oil change) ensures even wear and prolongs tire life. Stick to a consistent rotation pattern, such as crossing tires from front to rear diagonally. For vehicles with a full-size spare, include it in the rotation schedule to maximize usage. Many tire sellers also offer lifetime rotation services to make maintenance easier.
