How to Determine Whether Tire Pressure is High or Low?

[McPiper]

Methods to determine tire pressure: 1. Kick the tire a few times with your foot. If you feel vibrations and it is very jarring to your foot, it indicates sufficient tire pressure. 2. Observe the tire tread. Generally, if four or five tread blocks are in contact with the ground, it proves that the tire pressure is adequate. 3. Use a professional tire pressure gauge. Start the vehicle, put it in neutral, engage the handbrake, plug one end into the car's cigarette lighter, and connect the car tire inflator to the tire. Effects of high or low tire pressure: 1. Overinflated tires: When hitting bumps on the road, the lack of cushioning can easily cause a blowout. The tire itself is also prone to abnormal wear. 2. Underinflated tires: Increased rolling resistance leads to higher fuel consumption. It also causes abnormal tire wear. Additionally, low tire pressure can cause the tire to overheat severely, making it prone to standing waves and sudden blowouts at high speeds, which is very dangerous.
