Why do they leave colored lines on new tires and whether to take such rubber

When buying new tires for a car, everyone noticed on the tread the multi-colored stripes bordering the wheel. The lines are blue, red and yellow. After a short time, they disappear from the tire, rubbing off on the asphalt, leaving the owner bewildered. After all, for some reason, these lines were drawn?

What kind of stripes are drawn on the new rubber

As always, in such cases, when there is no official information, all kinds of rumors and speculations are born.

On wheels with the same size and tread pattern, there may be lines of different color and number

Theories explaining the origin of color stripes

Here are a few common versions that are actively discussed on the forums of motorists.

1. Some people think that the lines represent the type of rubber from which the tire is made.
2. Another opinion is that the manufacturer produces additional markings in order to combat counterfeits.
3. There is also an opinion that in this way the factory marks the defective wheels.

As you can see, the consumer is most concerned with the quality of the purchased products. Hence, there are many questions and concerns around this topic. Nobody wants to buy a fake or "substandard"!

But there are other opinions, more related to the technology of production and storage of tires.

1. Colored stripes are applied during tread formation. The rubber sleeve is initially made in a solid strip and then cut to fit the wheel. Marking prevents workers from confusing workpieces during assembly.
2. The lines serve as identification marks for warehouse workers. The fact is that, according to the developers' technology, the storage of tires is allowed only in an upright position, when the marking on the side surface is not visible.
   

   Tires are stored vertically on racks

Why are these stripes in reality

In fact, everything is much simpler! The lines indicate the shift in which the wheel was manufactured. In addition, there is a rectangular "stamp" on the side surface. It has numbers indicating the collector. Thus, the company declares responsibility for the quality of its products. When a defective wheel is found, you can always determine the time of its manufacture, as well as the identity of the employee.

The lines on the rim of the tire are erased no earlier than after 2 thousand kilometers. And the numbers in the square remain clearly distinguishable for the entire service life. This is, in fact, the personal stigma of the master and the brigade.

What does stripe color mean

In light of the above, it becomes clear that the color of the stripe is a symbol that the factory management accepts for internal use. There is no point in puzzling and making assumptions. Moreover, create a problem around this.

Many controversial issues have a simple explanation. The main accompanying document of the tire is the technical passport. It reflects the technical characteristics of the wheel, information about the manufacturer, and indicates the warranty. Only the technical passport is legally valid in the event of a dispute.
