Please suggest me about tyres

Summer tyres do not work because the rubber compound used to make summer tyres are designed to withstand high temperatures and to provide grip at those temperatures. In the winter, the summer tyres will become hard and not as flexible which means the grooves and tread blocks cannot dig into the snow. In addition, the tread design of summer tyres are designed to expel water and not snow.

Winter tyres are designed specifically for lower temperatures (And thus they cannot be used in the summer). They're of a softer compound to allow for greater flexibility and more aggressive tread designs help dig into the snow.

Winter tyres fall into two categories - snow and ice. You have to decide which you're more likely to encounter (is your area a snowy place or is it a place that doesn't snow often and the snow just sits around and melts because of the heat from cars driving on the road and turn to ice?). You also have to decide whether you need studs or not installed on the winter tyres
