What does it mean to check tire pressure?

[Nevaeh]

Checking tire pressure refers to the situation where one or more tires have insufficient or excessive air pressure, triggering a tire pressure warning. Both under-inflation and over-inflation can lead to abnormal tire wear, shortening the tire's lifespan, increasing fuel consumption, and even raising the risk of a blowout. Tire pressure is the air pressure inside the tire, and its level significantly impacts the vehicle's performance and power, including ride comfort and load capacity, as well as the tire's lifespan. Proper tire pressure is critical—whether too high or too low, it can drastically reduce the tire's service life.
