What could indicate subpar alignment during a safety inspection?

Uneven tire wear patterns are a clear indicator of subpar alignment because they suggest that the tires are not making consistent contact with the road surface. When a vehicle's wheels are misaligned, it can lead to uneven distribution of weight and stress on the tires, resulting in some areas wearing more quickly than others. This can manifest as bald spots, cupping, or other irregular wear. In a safety inspection, noticing these patterns prompts further investigation into the alignment of the vehicle, as proper alignment is crucial for safe handling, tire longevity, and overall vehicle performance.

Excessive fuel consumption may relate to other mechanical issues or driving habits but does not directly indicate alignment problems. Similarly, vibrations during acceleration can be caused by a variety of factors, such as tire balance, drivetrain issues, or even the condition of the suspension system. Noise from the engine is primarily associated with engine performance rather than alignment. Therefore, the observation of uneven tire wear patterns stands out as the most direct sign of potential alignment issues during a safety inspection.
