Why is it important to balance tires on a vehicle?

1. To enhance braking efficiency

2. To ensure even tire wear and improve ride quality

3. To maintain a constant speed

4. To increase the tire's lifespan

The correct answer is: To ensure even tire wear and improve ride quality

Balancing tires is crucial primarily to ensure even tire wear and improve ride quality. When tires are not balanced, it can lead to uneven distribution of weight, causing certain areas of the tire to wear out faster. This uneven wear can lead to a shorter lifespan for the tires as they may need to be replaced earlier than those that are properly balanced. Additionally, an unbalanced tire can lead to vibrations while driving, which not only makes the ride uncomfortable but can also negatively impact the vehicle's suspension system over time. Properly balanced tires help to maintain a smoother driving experience and contribute to overall vehicle performance. The other options touch on important aspects of tire and vehicle performance, but they do not directly relate to the primary purpose of balancing tires. While balanced tires can contribute to improved braking efficiency, maintaining constant speed, and potentially increasing tire lifespan, the key reason for balancing is the promotion of even wear and ride comfort.
