Additional signs on tires

The name of the manufacturer, production year, model name and its size are always indicated on the tire. The wheel marking by the manufacturers uses an alphanumeric code that represents the properties of a model, its technical specifications and features of operation. In addition to the basic indicators, the additional symbols are present on the tire sidewall.

1 - maximum load and pressure (US Standard);

2 - designation of the internal side in the case of the asymmetric tread pattern. The outer side is marked as "OUTSIDE";

3 - the number of layers and the type of cord carcass and the belt;

4 - the trademark of the manufacturer;

5 - profile width;

6 - series;

7, 15 - designation of the radial tire;

8 - the designation of the tubeless tires;

9 - bore diameter;

10 - the index of load;

11 - speed index;

12 - the direction of rotation of the car mounted tire (with directional tread pattern);

13 - the date of manufacture, e.g. 28th week of 2001 (before 2000 - a three-digit number);

14 - the UNECE Rule №30 compliance approval mark, the conditional number of the country that issued the certificate, and the certificate number;

16 - the model name.

Tires seasonality and operating conditions

  • RAIN, WATER or umbrella image notifies that the tires are specifically designed for wet pavement after rainy weather. These tires have a high level of protection against aquaplaning;
  • "Snowflake" icon or "Winter" notifies that it is a winter tire;
  • M&S stands for "Mud" and "Snow", so that tire can be used all-season long or in winter;
  • All Season – stands for the tire which is designed to use at any time of the year.

Installation signs

  • Left and Right are informing that this tire model should be mounted only on the left or right side. All these recommendations must be performed during fitting and stripping;
  • Outside and Inside indicate that the tire must be fitted, respectively, to the outer or inner side of the vehicle;
  • Rotation or an arrow icon indicates the direction in which the tire should rotate, which is associated with the direction of the tires tread pattern.

Color signs

Additional markings on the tires also include color designation on the sidewall. The colored labels in the form of the red and yellow point indicate the most rigid and the softest spot on the tire that should be considered when installing the camera on the rim.

White label with a numerical designation informs that the tire was checked by the inspector at the final stage of production. That sign has no meanings for the buyers or the tire store specialists.

Colored lines across the rubber serve to faster identification of the tire models in stores and warehouses. These strips could differ even on each model from the same manufacturer. They do not reflect any technical information about the tire.

Tires marking by manufacturers

When provided as a standard equipment the tire has a special mark indicating that it has been fitted during the assembly on the factory. Usually, this tire differs from its model standard as its technical parameters are optimized and chosen for the car target model to achieve maximum efficiency and performance. In this case, the "homologation" mark is used.

Some special marks and labels may indicate the common technical features of a tire or reflect its individual qualities which could restrict the fitting possibility on a certain brand or car model. To understand such markings properly one should be familiar with them in advance. Otherwise you can ask for help from our specialists, who are always ready to answer your questions.
