Which of the following is a benefit of proper suspension system maintenance?

The benefit of proper suspension system maintenance lies in its direct impact on vehicle handling and tire performance. A well-maintained suspension system helps ensure that the vehicle's tires maintain optimal contact with the road surface. This enhances steering precision and provides better control, particularly during turns or when navigating uneven terrain. Additionally, a properly functioning suspension mitigates excessive tire wear by allowing for even distribution of forces across the tires, thus prolonging their lifespan. This is crucial for safety and efficiency, making option A the most relevant benefit of proper suspension maintenance.

In contrast, the other options pertain to different vehicle systems or performance aspects that do not directly correlate with suspension maintenance.
