Summer tyres with M/S identification

Hello At a large tyre shipper I bought 4 tyres of the brand Fate AR300 175/70 R14 84T with M/S identification. The tyres were offered there as full-year tires. When I had the tires installed by a assembly partner of the shipper I was told that these tyres are only summer tires. I then listened around and found that other suppliers give the following hint on this tire. Quote: Since the company Fate also matures for the American market These tyres have an M/S identifier. This identifier has nothing to do with our all-year tyres. This tyre is a pure summer tyre. However, a large German Autombilclub could not give me any binding information, to the question what I now have for tyres on the car.
