What Does Excessive Tire Pressure Mean?

Tire pressure that is too high refers to the situation where the air pressure inside a car's tires is elevated beyond the safe range, which can pose safety hazards. Tire pressure indicates the air pressure within the tire and plays a crucial role in the vehicle's performance and power. Tires consist of three main parts: the outer tire, inner tube, and bead filler. The inner layer of the tire features a rubber layer with excellent airtightness, contributing to the trend of making tires lighter. The outer tire is primarily composed of the carcass cushion, tread and sidewall, and bead. Tires are circular, elastic rubber products mounted on vehicles or machinery, typically fitted onto metal rims. They support the vehicle's weight, absorb external shocks, ensure contact with the road surface, and maintain driving performance. Tires often operate under complex and demanding conditions, requiring high load-bearing capacity, traction, and shock absorption capabilities.
When I first learned to drive, overinflated tires meant pumping too much air. For example, my car's recommended pressure was 32 PSI, but as a beginner trying to save effort, I once inflated it to 38 PSI at once. As a result, the center of the tire bulged significantly, reducing the contact area with the ground and noticeably decreasing traction. The car felt unstable when turning, and even small stones on the road caused excessive bouncing, greatly reducing comfort. More importantly, prolonged overinflation caused the center of the tire to wear out much faster, cutting its lifespan in half and increasing the risk of blowouts during hot summer temperatures. After that lesson, I developed a habit of using a tire pressure gauge weekly to keep it within the recommended range. Safe driving is fundamental—don't let small issues cause big trouble. Additionally, tire pressure fluctuates with seasonal changes, dropping in cold weather and rising in hot weather, so timely adjustments are necessary to avoid exceeding limits.
