Tire pressure isn’t just about avoiding blowouts—it directly influences key vehicle performance metrics. Proper inflation optimizes fuel efficiency: underinflated tires increase rolling resistance, reducing gas mileage by up to 3%. For example, a 10% drop in pressure can lower fuel economy by 1-2 mpg. Handling and braking also depend on correct pressure: underinflated tires feel sluggish in turns, while overinflated ones reduce traction, lengthening braking distances by 10-15% on wet roads. Ride comfort is another factor—overinflated tires transmit more road vibrations, while underinflated ones may cause a “soft” steering feel. For performance vehicles, precise pressure (matching manufacturer’s sport settings) enhances cornering grip. Even daily commuters benefit: maintaining optimal pressure reduces engine strain and extends not just tire life, but also suspension component longevity. By linking pressure checks to performance, you maximize both safety and driving experience.
