When tire pressure strays from recommended levels, it can lead to adverse effects on both fuel economy and driving performance.
How Tire Pressure Affects Overall Performance
Correct tire pressure maximizes the tire’s contact with the road, which is crucial for minimizing rolling resistance. Underinflated tires result in a larger contact area, increasing resistance and prompting the engine to work harder. This scenario is evident in fuel economy research, indicating that proper tire inflation can reduce fuel consumption by as much as 2%. A 1 PSI drop in tire pressure results in a 0.2% decrease in gas mileage, a statistic backed by the U.S. Department of Energy.
Research Findings on Tire Pressure and Fuel Economy
Research conducted by Oak Ridge National Laboratory highlighted the dramatic impacts of tire pressure on fuel economy. When all four tires were at only 75% of the recommended pressure, fuel economy decreased by 2-3% over various speeds. More strikingly, at just 50% of the recommended tire pressure, fuel economy dropped by approximately 10% when traveling at 40 miles per hour and by 5% at 80 miles per hour. This research emphasizes that insufficient tire pressure directly leads to increased fuel consumption, confirming that tire pressure effects cannot be overlooked when striving for better driving performance.
Additionally, rolling resistance increases with lower tire pressure, having a considerable impact on fuel economy. Deformation losses from tires at improper pressures contribute significantly to energy use in vehicles, accounting for a large share of fuel consumption in urban cycles. By ensuring tires are properly inflated, you not only enhance performance but also actively contribute to fuel savings and environmental conservation.
