Properly inflated tires do which of the following?

Properly inflated tires play a significant role in various aspects of vehicle operation. When tires are maintained at the correct pressure, they contribute to fuel efficiency, as under-inflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Therefore, properly inflated tires help save fuel.

In terms of traction, tires that are inflated to the correct levels ensure that the contact patch with the road is optimized. This enhances grip and stability, allowing for better handling during driving, especially in adverse weather conditions, thus increasing vehicle traction.

Additionally, maintaining the right pressure in tires means they wear evenly and last longer. Under-inflated tires can lead to uneven wear patterns and potentially cause damage that shortens tire life. Well-inflated tires contribute to prolonging their longevity.

Finally, proper inflation directly influences overall vehicle performance. This includes factors such as ride comfort, responsiveness, and the vehicle's ability to handle various driving conditions effectively.

Hence, all these benefits—fuel savings, increased traction, prolonged tire life, and improved overall performance—combine to justify that properly inflated tires yield numerous advantages, making "all the above" the most comprehensive and accurate answer.
