When people generally say "thick" or "thin", they should be talking about tires. The combination of car steel rims and car tires is mainly determined by the car. When we refit, the diameter of the wheel hub increases, so the width increases, while the thickness of the tire becomes thinner when the diameter and width increase. In fact, the reason is very simple. The main reason is that if the thickness of the tire remains the same, the wheels will wear the car body, so thin tires and thick tires are much more expensive.
Because reliability must be ensured first, and the rubber strength of thin tires must be much higher than that of thick tires, the air in the tires will decrease, and the resistance to friction and collision will be greatly weakened, so the quality of thin tires is much higher. And because the tire has a certain shock absorption function, the larger the wheel hub, the thinner the tire, and the thinner the tire, the less obvious the shock absorption effect. When extreme driving, the tire variant is smaller, so it is good for handling, and the safety is increased, but the comfort is weakened, so the thicker the sidewall, but the effect will be opposite to that of the thin tire.
