Uneven tire wear on a motorcycle is most likely caused by which issue?

• A. Incorrect tire pressure
• B. Incorrect wheel alignment
• C. Worn brake pads
• D. Low fuel

Answer: (B)

Uneven tire wear happens when the tire doesn’t roll in a perfectly straight line, so one edge bears more load than the other. This is most likely caused by incorrect wheel alignment. When the wheels aren’t aligned, the tire’s contact patch is skewed, wearing one side faster and sometimes producing a cupped pattern. Correcting alignment lets the tire sit evenly on the road and wear evenly over time. Tire pressure can affect wear patterns, but it doesn’t usually create a pronounced side-to-side wear like misalignment does. Worn brake pads and low fuel don’t cause this wear pattern.
