How does tire pressure affect fuel efficiency?

Tire pressure plays a crucial role in maintaining fuel efficiency of a vehicle. When tires are properly inflated, they can optimize fuel consumption and improve gas mileage.

Low tire pressure increases the rolling resistance, which means the engine needs to work harder to move the vehicle. This, in turn, leads to increased fuel consumption. According to studies, for every 1 psi (pound per square inch) drop in tire pressure, fuel efficiency can decrease by up to 0.3%.

On the other hand, overinflated tires can also negatively impact fuel efficiency. Overinflation can cause uneven tire wear, resulting in reduced traction on the road and potential loss of control. This can lead to decreased fuel efficiency as the vehicle's handling and stability are compromised.

To maximize fuel efficiency, it is recommended to maintain tire pressure at the manufacturer-recommended level. Regularly checking and maintaining proper tire pressure not only improves fuel efficiency but also ensures safety on the road.
