Imagine that you ordered new tyres and after receiving the delivery you want to see the whole set. You open the package and you see your new tyres with treads marked with colourful stripes. If you ever experienced such a situation, you already know that there is nothing to worry about. Those who are uncertain, though, should read this article.
Even the biggest tyre manufacturers with an established market position must offer technologically advanced products (unique or better than those offered by the competition) to remain among the best.
That is why professionalism is so important throughout the entire production and distribution process of tyres. Every day, tyre factories produce thousands of tread sheets, so it was necessary to develop an appropriate system of marking them to avoid costly mistakes.
This explains the presence of coloured stripes or alphanumeric codes that precisely indicate the type, size and other characteristics of a tyre model.
What information is indicated by the stripes?
The stripes are important only from the point of view of the production plant; they facilitate the work of professionals and factory workers. For an average user, they have no meaning.
The stripes wipe out after a few days of using the tyre.
Symbols, stripes or lines are associated with a particular plant, where the tyre was produced. It may happen that the same model in the same size will be marked with a differently arranged colour stripes. Don't worry if after receiving the delivery, you realise that one of the tyres has a different colour marking than others.
What is the meaning of dots marked on tyres?
Colourful dots on the side of the tread are important for manufacturers, as in the case of stripes. The operational value an average driver is close to zero.
Depending on the particular manufacturer, they may inform, e.g., about:
the maximum deflection of the variable radial force (red dot on the tyre for Bridgestone tyres)
valve position - this is the mounting information, which is often a form of agreement between the tyre manufacturer and the car producer, which purchases a larger batch of the product for its car model,
successfully passed quality tests (white dot with a black centre)
Please note that the dots of the same colour may have completely different meaning for different suppliers. The meaning of these dots is variable, depending on the manufacturer, and even within the same brand but for different models.
