What is the method for checking car tire pressure?

[DiJeffrey]

The method for checking car tire pressure is: 1. Unscrew the tire valve cap; 2. Press the tire pressure gauge onto the valve; 3. Press the tire pressure gauge all the way down; 4. Observe the pointer and read the measured tire pressure value. Hazards of low tire pressure: 1. Increases the contact area between the tire and the ground, causing abnormal temperature rise inside the tire during driving; 2. Severe deformation of the tire sidewall accelerates the aging of internal steel wires and fabric layers, leading to tire blowouts; 3. Increases fuel consumption and reduces tire lifespan. Factors affecting car tire pressure: 1. Seasonal factors: Thermal expansion and contraction in summer and winter result in different tire pressures; 2. Load conditions: Tire pressure varies when the vehicle is empty, half-loaded, or fully loaded; 3. Tire condition: Worn tires and unworn tires have different tire pressures.
