What Do the Yellow and Red Dots on Tires Represent?

[VanVivian]

Here are the meanings represented by the yellow and red dots: 1. The solid red dot indicates the position with the maximum longitudinal vibration of the tire, meaning this is the heaviest spot, referred to as the center of gravity in technical terms. As we all know, tires generate vibrations during rotation, and this spot is where the vibration is the strongest. 2. The hollow yellow dot is the opposite of the solid red dot, representing the position with the minimum longitudinal vibration of the tire, meaning this is the lightest spot, known as the tire's light point. Here is some additional information: In addition to the two dots on the tire, some wheel rims also have markings—a solid white dot. Some rims may not have this marking. This solid white dot represents the light point of the rim, indicating the lightest position.
