What is the use of a yellow and red circle on the side of a car tire?
Red dot is representative of the uniformity of it, yellow point this is aligned with the valve.
Yellow point that the tire static balance point, that is, the most light point, filling the door where the red dot that the tire radial size of the largest point of white point that the dynamic balance point
Hello, the main thing is the two roles: the valve and tire when installed inside and outside can distinguish. And then a role is the role of decoration, very good to see my personal feel that you want to answer to help you.
If you are referring to Michelin's tires, the red dots represent the tire's longitudinal rigid maximum position. The yellow hollow point is called the trolley mark, indicating that the position is the lightest part of the tire's circumference. When replacing the tire, it must be installed in alignment with the valve on the rim with the heaviest position in order to keep the wheel running Best balance.
1, the yellow point on the tires for the hollow yellow point, is the tire radial vibration of the smallest point, can be understood as the tire "light". Yellow dot position in the tire circumferential the most light, is the balance of qualified signs. 2, the tire side has only one red dot, and solid red dot, is the markings of the tire stiffness. Solid red dot is the tire longitudinal rigid maximum position, is the solid red dot is the tire in the rotation of a circle when the vibration of the largest point, the vibration value is too large when the tire will produce vibration, so a good manufacturer in the new product testing Found that the value of vibration will not let it off the factory. There are red tires in theory The production process is not particularly good, the material is not uniform, so the standard red and yellow. And the production process of good tire texture uniform, no need to mark the red dot.
