The colored dots on the tires of some cars are key to their correct assembly and, therefore, to the safety and dynamic behavior of the vehicle.
The best known is the red dot, which can be in the shape of a point or triangle, and makes it easier to balance the tire by marking the maximum point of radial force variation (RFV), a defect that is impossible to see with the naked eye. , but it exists, since no tire is perfect in terms of shape and structural rigidity.

At the same time, the rim is also not completely uniform. That is the reason why some have a mark that indicates the point where their weight is greatest and generates more centrifugal force when rotating on their axis.
Both brands are taken into account when mounting the tire to better calibrate the assembly using counterweights.
What do the rest of the colors mean?
Yellow dot: indicates that the tire is lighter and also works as a reference when balancing it, making it coincide with the point on the rim where the inflation valve is located. White dot: indicates the place of variation of radial force (RFV). ) minimum, that is, the area where the tire has its greatest flexibility, unlike the maximum RFV indicated by the aforementioned red dot.
The detail of the data recorded on the tire
The numbers stamped on tires provide important information about the tire's features and specifications. These numbers and letters are codes that include details such as size, load capacity, maximum speed and other relevant data.
They can usually be found on the side of the tire and may look something like “P205/60R16″ or “225/45ZR17″. Here is a brief description of what they mean:
“P” or “LT”: Indicates the type of tire, where “P” means passenger tire and “LT” means light vehicle tire. Three-digit number (for example, “205″ or “225″): Represents the width of the tread in millimeters. Aspect ratio (for example, “60″ or “45″): Shows the relationship between the height of the sidewall and the width of the tread in percent. “R”: Means that the tire has radial construction. Two-digit number (for example, “16″ or “17″): Indicates the diameter of the rim in inches. Load index: A number that shows the maximum load capacity that the tire can support .Speed Symbol: A letter indicating the maximum speed at which the tire is designed to operate safely.
These numbers are essential to ensure you are using the right tires for your vehicle and to maintain safe performance on the road.
