Operating a vehicle with underinflated tires presents numerous safety and efficiency challenges. This condition occurs when the air pressure within a tire falls below the manufacturer’s recommended level, often indicated on a sticker located in the driver’s side doorjamb or the vehicle’s owner’s manual. For instance, a tire requiring 35 psi (pounds per square inch) would be considered underinflated if its pressure measured 30 psi.
Maintaining correct tire pressure is crucial for optimal vehicle performance, safety, and tire longevity. Underinflation increases rolling resistance, reducing fuel economy and increasing emissions. It also generates excessive heat within the tire, accelerating wear and increasing the risk of tread separation or blowouts. Furthermore, compromised handling and braking performance can result, increasing the likelihood of accidents. Historically, tire pressure monitoring systems (TPMS) have become increasingly common in modern vehicles, reflecting the recognized significance of proper inflation. These systems alert drivers to low pressure situations, promoting safer driving conditions.
