Maintaining the correct tire pressure is crucial. Under-inflated tires can lead to poor vehicle handling and increased tire wear, while over-inflation can cause a harsh ride and could make the tires more prone to blowouts. According to the National Highway Traffic Safety Administration (NHTSA), maintaining proper tire pressure can improve fuel efficiency by 3.3%, which translates to savings and reduced environmental impact.
What Are the Risks of Driving with Incorrect Tire PSI?
Driving with incorrect tire PSI (pounds per square inch) poses several risks. These risks include diminished vehicle safety, decreased fuel efficiency, and accelerated tire wear.
- Diminished Vehicle Safety
- Decreased Fuel Efficiency
- Accelerated Tire Wear
Driving with incorrect tire PSI diminishes vehicle safety. When tire pressure is too low, tires may overheat, increasing the risk of blowouts. According to the National Highway Traffic Safety Administration (NHTSA), under-inflated tires contribute to approximately 11,000 accidents annually. Conversely, over-inflated tires can lead to reduced traction and longer stopping distances.
Decreased fuel efficiency occurs when tires are not inflated to the recommended PSI. Under-inflated tires create more rolling resistance, leading to higher fuel consumption. The U.S. Department of Energy states that proper tire inflation can improve gas mileage by 0.6% to 3%. This might not seem significant, but it accumulates over time and affects overall vehicle operating costs.
Accelerated tire wear is a significant consequence of incorrect tire PSI. Under-inflation causes tires to wear unevenly, leading to premature replacement. A study conducted by the American Automobile Association (AAA) found that 25% of surveyed drivers had at least one under-inflated tire, which can reduce tire lifespan by 25%. This additional expense can strain a driver’s budget and disrupt vehicle performance.
