According to the U.S. Department of Energy, proper tire inflation improves fuel economy by optimizing the tires’ performance. Under-inflated tires can reduce fuel efficiency by 0.2% for each 1 psi drop in the average tire pressure.
Low tire pressure increases rolling resistance. Rolling resistance is the force that opposes the motion of a tire as it rolls along the ground. This force increases when tires are soft or under-inflated because they deform more as they rotate. Additionally, under-inflated tires create more heat due to increased friction with the road surface. This heat contributes to energy loss, further reducing fuel efficiency.
In technical terms, rolling resistance is typically influenced by factors such as tire construction, tread design, and tire pressure. When tires are low on pressure, their contact area with the road increases. This larger contact patch leads to greater deformation as the tire rotates, causing more energy to be consumed.
Specific conditions that contribute to increased fuel consumption due to low tire pressure include driving on rough terrain or uneven surfaces. For example, if a vehicle with low tire pressure is driven on gravel roads or pothole-filled streets, the increased bouncing and shape changes of the tires will further increase energy loss. Regularly monitoring tire pressure and maintaining it at manufacturer-recommended levels can significantly improve fuel economy and extend tire life.
