Summer tyres are not intended for cold weather and will not grip in snow or ice conditions. These tyres offer maximum grip and handling on dry and wet roads.
Winter tyres have a tread with more sharp edges for better grip on snow and ice than all-season tyres, and many have a softer rubber compound that stays flexible in extremely cold temperatures.
All-season tyres fit everything, available from small cars to light SUVs and pickups (and come standard on many sedans and city cars). They are designed to handle most conditions, including dry and wet asphalt, and light to moderate snow.
