You should only drive with snow chains when it is absolutely necessary. Don't leave them on your car all the time during winter.
Snow chains, or tire chains, are devices fitted to the tires of vehicles to provide maximum traction when driving through snow and ice.
Snow chains attach to the drive wheels of a vehicle. Chains are usually sold in pairs and must be purchased to match a particular tire size (tire diameter and tread width). Driving with chains reduces fuel efficiency, and can reduce the speed of the automobile to approximately 50 km/h (30 mph).

Snow tires are tires designed for use in colder weather, snow and ice. Snow chains can be a slower-speed, temporary alternative in snowy conditions.
Snow tires have more sipes than summer tires, increasing traction on snow and ice, but reducing grip on dry and wet roads. Tires designed for winter conditions are optimized to drive at temperatures below 7 °C (45 °F).
Snow removal is the job of removing snow after a snowfall to make travel easier and safer. This is done by both individual households and by governments and institutions.
