What are the yellow and red dots on tires?

[SanElliott]

The hollow yellow dot is the light point mark of the tire, indicating the lightest position on the tire; the solid red dot represents the point of maximum longitudinal rigidity of the tire. Below is an introduction to the yellow and red dots on tires: 1. Introduction to the yellow dot: The hollow yellow dot is the light point mark of the tire, indicating that this position is the lightest on the tire. A car wheel consists of three parts: the tire, the rim, and the valve. The valve is installed on the rim and can correspond to the heaviest point on the rim. When assembling the tire, aligning the position marked with a yellow dot on the tire with the heaviest point on the rim can achieve better dynamic balance. 2. Introduction to the red dot: The solid red dot represents the point of maximum longitudinal rigidity of the tire, simply put, the position marked with a red dot is the point with the most vibration on the tire. When the vehicle rotates once on the surface, every position inside the tire will experience different degrees of compression force, which indirectly affects driving comfort.
