What Does Low Tire Pressure Mean?
2 Answers
Tire low pressure means that the tire pressure is too low and needs to be replenished. The effects of low tire pressure are: 1. It increases the contact area between the tire and the ground; 2. The steering wheel becomes heavier, affecting driving; 3. The tire is prone to overheating, increasing the risk of a blowout; 4. It causes the tire body to expand, making it more likely for cracks to appear on the inner and outer sides of the tire, accelerating rubber aging. The functions of tires are: 1. To prevent severe vibrations and early damage to automotive components, adapt to the vehicle's high-speed performance, and reduce driving noise; 2. Together with the vehicle's suspension, they cushion the impacts encountered during driving and dampen vibrations; 3. To transmit traction and braking torque, ensuring good adhesion between the wheel and the road surface to improve the vehicle's power, braking, and passability; 4. To support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions.
Low tire pressure essentially means the air pressure inside the tire is insufficient. The standard pressure value is usually indicated on a label attached to the door pillar, and anything below that value indicates a problem. Once, while driving, I felt the car was unstable and the steering wheel was shaking. After checking at the repair shop, it turned out to be caused by low tire pressure. Due to insufficient air, the tire's contact area with the road increased, leading to higher friction, a noticeable rise in fuel consumption, and poorer handling. Common causes of low tire pressure in daily driving include slow leaks, aging valve stems, or pressure drops due to cooler weather. I recommend using a portable tire pressure gauge to check the pressure once a month. Maintaining the correct pressure can save fuel, reduce tire wear, improve driving safety, and avoid the risk of unexpected blowouts at high speeds. Regular checks and timely inflation are key habits—don’t overlook this.
