What is the method for visually checking tire pressure with a diagram?

The method for visually checking tire pressure with a diagram is: By reading the value indicated by the pointer, you can determine the tire pressure. The tire pressure diagram is divided into an inner ring and an outer ring. The unit of the inner ring is kilograms per square centimeter, where 1.02 kilograms per square centimeter is equivalent to 1 bar. By converting the inner ring value, you can determine the tire pressure. Hazards of excessive tire pressure: 1. The friction and adhesion of the tire will decrease, affecting braking performance; 2. It can cause steering wheel vibration and deviation, reducing driving comfort; 3. It accelerates the localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; 4. It increases the vibration of the vehicle body, indirectly affecting the lifespan of other components.
Visually checking tire pressure is actually quite simple, and I often do it this way: First, find a flat place to park, then squat down and carefully observe the curvature of the tire sidewall. Under normal pressure, the tire should stand straight without bulging outward too much; if the pressure is insufficient, you'll notice the tire visibly sagging downward with both sides bulging like it's swollen. Diagrams usually show a comparison—one side with normal tire pressure where the edges are sharp and angular, and the other side with low pressure where the tire becomes round and deformed. I remember checking like this before a long trip and noticing one tire was a bit soft, so I quickly found a place to top it up. Although visual inspection isn't precise, it helps quickly spot major issues. I recommend making it a weekly habit and not ignoring signs of wear—safety comes first. Also, considering weather changes, tire pressure often drops in cold weather, so extra attention is needed.
