вот здесь правда объясняют, что несмотря на M+S маркировку не все AT могут считаться настоящей "зимней" резиной
M+S marking on tyres is very misleading.
Many AWD tyres are rated M+S, M&S or M/S, i.e., mud and snow. Established by the USA Rubber Manufacturers Association (RMA), the M+S designation refers only to the tread pattern. The M+S standard calls for a tyre with grooves at the outside of the tread that extend into the centre. It also means that 25% of the tyre tread contact surface be open, i.e., a more open tread pattern.
You will find the M+S symbol on most all-season tyres, on off-road and all-terrain tyres and even some high performance summer tyres may have this designation. However, there are no performance standards to meet or traction tests to pass. Any tyre with grooves at angles and with 25% of the tread void can be labelled as M+S.
And on icy snow and on ice, the open tread grooves have zero effect on performance. Control of the vehicle comes strictly from equal parts of the tyre rubber compound that provides adhesion and the effects from the tread sipes.
In 1999, the RMA defined a real “snow” or winter tyre with its severe snow-rating. Car and AWD tyres that pass this performance test and are embossed with the “snowflake on a mountain peak” icon. Severe snow-rated tyres must provide traction at least 10% better than a standard reference test tyre.
The off-road, all-terrain and all-season M+S tyres cannot pass this test. The M+S rating doesn’t mean much. The severe snow rating does.

Андрей Владимирович:
позволяют никогда не пользоваться тормозами?
это вопрос религии можно и на сликах тормозить, если с головой и хотя я тоже как и ты придерживаюсь мнения, что лучше на зиму на 4х4 полноценную шиповку, но даже многие мудовки от Нокиан будут намного лучше, чем какая-нибудь облизанная еврозима
