If your tires have worn unevenly, what might be causing this?

• A. Incorrect tire pressure
• B. Incorrect wheel alignment
• C. Worn tread from braking
• D. Damaged suspension

Answer: (B)

Uneven tire wear happens most often when the wheels aren’t pointing straight—the brakes and steering angles aren’t aligned with the road. When alignment is off, the tire doesn’t sit flat on the road across its surface, so one edge wears faster than the other or a particular area wears more, shortening tire life and affecting handling.

Other patterns can come from tire pressure or suspension issues, but they wear in different ways: over- or under-inflation tends to wear the center or the edges rather than just one edge, and suspension damage can cause irregular wear but is less directly tied to a single uneven edge.
