From another forum and allegedly from Autobild: Quotation: The much-quoted “7-degree fairy tale”, which has been used by the tire industry for a few years for targeted disinformation, is unfortunately hardly to be eradicated. The argument of the tire manufacturers reads as follows: Even if there is no snow, winter tyres are better, because already below +7C a summer tire is hard and therefore on wet or dry road is worse than a winter tire. car photo has tested and the summer tyre was better than the winter tyres in winter: brake routes from 100km/h with wet roadway: summer tyres: 49.3 m best winter tyres: 54.4 m brake routes from 100km/h with dry roadway: summer tyres: 38.7 m best winter tyres: 45.6 m”Best brake tyres on dry and wet roadside are the summer tyres with a clear distance. On grippy asphalt The soft, laminated running surface of the winter tires becomes a handicap, especially at temperatures above freezing point.” “Surprise: When it comes to the disciplines handling and braking (wet and dry), all winter candidates draw the shorter compared to a summer tire. A sign for the quite one-sided black and white design for snow. It is easy to understand that they have a look on dry asphalt – the less stable profile blocks cannot be enough H The fact that they cannot pass the water to the summer candidate on scattered, wet (i.e. smoother) roads is not a good testimony. The sport-oriented driver should remember this and not overestimate his winter tires in this respect.” If so, aren’t winter tires more likely to be a risk in mild winters?
