What is a potential consequence of driving with improperly inflated tires?

Driving with improperly inflated tires significantly influences the vehicle's fuel efficiency. When tires are under-inflated, they create more rolling resistance, meaning the engine has to work harder to move the vehicle. This increased effort leads to higher fuel consumption. Conversely, over-inflated tires can also lead to inefficiencies, as they may not have enough contact with the road, resulting in a poor grip and thus requiring more energy for acceleration.

Proper tire inflation contributes to optimal fuel efficiency, ensuring that vehicles operate as intended without unnecessary strain on the engine. The correct tire pressure helps maintain the tire’s shape and reduces wear, aiding in preventing fuel economy loss.

Considering other options: while improper inflation can negatively impact stopping distances, traction on wet surfaces, and tire lifespan, the primary and most immediate consequence seen by most drivers is the reduction in fuel efficiency.
