Red and yellow dots on new car tires: The red dot indicates the position with the maximum longitudinal vibration of the tire, meaning this is the heaviest part, referred to as the center of gravity in technical terms. The yellow dot indicates the position with the minimum longitudinal vibration of the tire, meaning this is the lightest part, known as the tire's light point. Car tires are one of the key components of a vehicle, directly contacting the road surface and working with the car's suspension to mitigate the impacts encountered during driving. They ensure good ride comfort and smooth driving, maintain excellent adhesion between the wheels and the road, enhance the vehicle's traction, braking, and off-road capabilities, and bear the weight of the car. The crucial role tires play in automobiles is increasingly being recognized by people.
