By now we should all know that Michelins summer-bias all season tyre is different. 

Traditionally all season tyres start as winter tyres, and have a little extra dry and wet performance added into the mix. While this leaves traditional winter-bias all season tyres performing excellently in the snow, they give up around 15% dry braking performance when compared to a summer tyre, which affects braking for the 200+ days dry running we get in the UK.

The summer-bias Michelin CrossClimate started life as a summer tyre, and as such does not give up the dry braking performance traditional all season tyres do. Does this mean they don't perform in the snow and ice? We head off to the Swiss Alps to find out.
