What's the difference between summer and winter tyres?
Summer tyres oftern are designed in such a way that means the tread becomes clogged with snow, ice or slush, reducing grip and control.
Winter tyres are designed with snow and ice in mind and therefore have much deeper treads nd utilise sipes to create small bites in the surface. Sipes are small incisions down the edge of the tread blocks.
Due to the wider more uniform nature of winter tyres there is a more gradual shift between the tread blocks and snow is displaced instead of being compacted creating an icy surface with little grip.
Winter tyres also use a higher concentration of rubber in them granting increased levels of flexibility and therfeore grip during colder weather.
