- Reduced traction
These risks highlight the potential issues when tire pressure is significantly below the recommended level. Understanding the implications of low tire pressure helps underscore the importance of regular vehicle maintenance.
-
Increased Tire Wear:
Having a tire pressure of 20 PSI leads to increased tire wear. Low pressure causes the tires to flex excessively, resulting in more friction with the road. This accelerates tread wear and can reduce the tire’s lifespan. According to the U.S. Department of Energy, under-inflated tires can wear out faster by up to 25% compared to properly inflated tires. -
Poor Handling and Control:
Poor handling and control occur when tire pressure is too low. Low-pressure tires can make the vehicle feel sluggish and unresponsive. This complicates steering and may lead to a higher risk of losing control during a sudden maneuver. The National Highway Traffic Safety Administration (NHTSA) stresses that maintaining proper tire pressure is vital for safe vehicle handling, especially in adverse weather conditions. -
Reduced Fuel Efficiency:
Reduced fuel efficiency arises from under-inflated tires. Tires with low pressure create more rolling resistance on the road, forcing the engine to work harder. The U.S. Department of Transportation estimates that a loss of just 1 PSI can decrease fuel efficiency by approximately 0.2%. Thus, having tires at 20 PSI can substantially increase fuel costs over time. -
Risk of Tire Blowout:
The risk of tire blowout is significant with a pressure as low as 20 PSI. Low pressure increases the heat buildup in tires, which can lead to structural failure.
