Which of the following statements is true regarding truck tire inflation?

Correctly inflated tires play a critical role in enhancing fuel efficiency in trucking operations. When tires are inflated to the manufacturer’s recommended pressure, they maintain optimal contact with the road surface, which reduces rolling resistance. This means the engine does not have to work as hard to move the vehicle, leading to improved fuel economy. Additionally, properly inflated tires prevent uneven tire wear and contribute to better overall vehicle handling and stability.

In contrast, under-inflated tires can lead to increased rolling resistance and poor fuel efficiency, as the truck requires more energy to move. Other options suggest misconceptions about tire inflation, with implications for vehicle performance, stability, and fuel consumption that do not hold true. This makes the understanding of proper tire inflation crucial for any commercial driver seeking to maximize efficiency and safety on the road.
