How Can Low Tire Pressure Extend Stopping Distances?
Low tire pressure can extend stopping distances due to reduced tire contact with the road, altered vehicle handling, and increased rolling resistance. Each of these factors plays a significant role in a vehicle’s braking performance.
Reduced tire contact: When tire pressure is low, the tire becomes less rigid. This deformation increases the amount of tire surface that is in contact with the road. Although one might think more contact would improve traction, it actually leads to a larger contact patch that can decrease the tire’s ability to grip the road effectively. According to a study by the National Highway Traffic Safety Administration (NHTSA, 2018), a vehicle with low tire pressure faces a 20% reduction in contact efficiency, directly impacting stopping distances.
Altered vehicle handling: Low tire pressure negatively influences how a vehicle steers and responds to braking. Under-inflated tires can lead to slower steering response and less predictable handling. This can result in longer reaction times for drivers who may need to brake suddenly. The University of Michigan’s Transportation Research Institute (UMTRI, 2020) found that reduced handling precision can add up to 30% more time to stop.
Increased rolling resistance: Low tire pressure increases the rolling resistance of tires. This means the engine has to exert more power to maintain speed. When a driver decides to stop, the extra effort required to overcome this resistance translates to a longer distance traveled before the vehicle fully stops. Research conducted by the American Automobile Association (AAA, 2019) indicated that 50% of drivers do not check their tire pressure regularly. This lack of maintenance can contribute significantly to increased rolling resistance and longer stopping distances.
These factors combined mean that maintaining proper tire pressure is crucial for safety. Regularly checking tire pressure can help drivers ensure effective braking performance and reduce the risk of accidents.
