Nije to ništa novo.
Imaš ECE pravilnik za gume, pogledaj ga.
Bila je diskusija apropo ovoga u ovoj temi, pa reko da stavim da vide ljudi, jer niko nije kacio do sad konkretan primer.

Snow tyres definition
In the media, the regulations regarding the appropriate tyres are usually explained as the obligation to use snow tyres in Germany. It is indeed expected that the current regulations, which make it compulsory for drivers to adjust their tyres to weather conditions, will result in the obligation to have snow tyres. Over the past few months, there have been discussions about which tyres are considered appropriate snow tyres in this context and about the concrete definition of snow tyres. At this moment, there is no legally prescribed definition of snow tyres. However, the ECE regulation no. 30 of the EU directive 92/23 and § 36 of the German Strassenverkehrs-ZulassungsOrdnung do state that
snow tyres should always carry the indication M+S, M&S or M.S. This would mean that all tyres with an M+S indication (including some summer tyres) are considered appropriate snow tyres. Snow tyres should also have a minimum tread of 4 mm.
M+S tyres with snowflake symbol
Some tyre manufacturers decided to add the snowflake symbol to their M+S indication.
The use of the snowflake symbol on snow tyres is currently only compulsory in the United States and Canada. In the EU, it is only a voluntary indication that is not regulated by law. However, established US tests have shown that tyres with the snowflake symbol have 10% more traction on a snowy road surface than tyres without this symbol. The meaning of the snowflake symbol is also unmistakable to both tyre expert and consumer. The snowflake symbol is also sometimes used as part of the so-called 4-seasons symbol. This symbol does not reflect anything about the tyre’s qualification as a snow tyre. A 4-seasons tyre with such a can only be considered as a snow tyre if the tyre is also showing M+S in combination with the snowflake symbol (separately).
