How do winter tyres work?

Winter tyres are designed to significantly improve traction and control on icy or snow covered road surfaces with optimum performance below 7c. The rubber compound that is used to manufacture winter tyres means that it retains its elasticity and ability to grip during cold weather, compared with summer tyres that usually firm up or become rigid reducing grip.

There is much higher concentration of natural rubber in winter tyres in order to retain this elasticity.
