Question: 1 / 400

Why is proper tire inflation important for a combination vehicle?

To improve the appearance of the vehicle

To ensure optimal fuel efficiency and safety

Proper tire inflation is crucial for combination vehicles primarily because it ensures optimal fuel efficiency and safety. When tires are correctly inflated, they maintain their shape and provide the appropriate contact with the road surface, which enhances traction and handling. This optimal contact not only promotes better control of the vehicle but also helps in minimizing the risk of tire blowouts, which can lead to severe accidents.

Additionally, well-inflated tires contribute to better fuel efficiency. Under-inflated tires create more rolling resistance, which means the engine has to work harder to maintain speed, resulting in higher fuel consumption. Conversely, over-inflation can result in a harsher ride and uneven tire wear. Therefore, maintaining the correct air pressure in tires is a key aspect of vehicle maintenance that directly influences both safety and operational costs.
