Winter tyre options are mostly dependent on where you live and how you use your car. In addition what type of a vehicle you have matters. It is important that if you have winter conditions where you live or where you plan to drive, that you have tyres that are designed for those conditions. It can be very dangerous to drive with tyres that are not designed for winter use. So when you plan to drive in winter conditions, make sure that the tyres are approved for winter conditions. They should have a symbol on the sidewall of the tyre with a 3 Peak Mountain with a Snow Flake symbol inside the mountain. It is often referred to as the 3PMSF symbol. This is the proper winter symbol. The M+S indicating mud and snow is not sufficient for safe driving during winter conditions.
When you select winter tyres, you have basically two different types of dedicated winter tyres, meaning that they are to be used only during the winter season and have to be changed to summer tyres for driving during the other seasons. One is the studded tyre, that has metal studs protruding from the tread to give you good grip on ice and has specially designed tread to provide the best performance on snow and slush. Then you have non-studded tyres, which have similar tread design for snow and ice and have then incorporated features for improving the grip on icy surfaces, so that they can compete with the studs. Both these will be safe options for driving during the winter season. It is important to invest in good quality tyres and to make sure that they are mounted on your vehicle during the whole time that you have winter conditions when you drive.
You have also a third option for areas where the winters are not that prevalent or that harsh, that is the all-weather tyres that if they are winter approved will work fine in winter conditions. They can also be used all year round, so that you are always ready to drive regardless of current or approaching weather. The last thing that you will need to ensure is that you have special tyres for SUVs, electric or hybrid cars, check that they are designed for that purpose.
