Winter tire chains are devices made of metal links that attach to the tires of vehicles to improve traction on snow and ice. They are particularly useful in harsh winter conditions, allowing vehicles to navigate slippery roads more safely. Installing tire chains can enhance grip and stability, making it easier to drive uphill or on icy surfaces. However, they should be used according to local regulations, as some areas have specific rules about when and where they can be used. Proper installation and removal are essential to avoid damage to both the vehicle and the road.
