Tire chains are devices made of metal links that are fitted around the tires of vehicles to improve traction on slippery surfaces, such as snow and ice. They are commonly used in winter conditions to help prevent slipping and sliding, making it safer to drive in challenging weather. When installing tire chains, it's important to ensure they are the correct size for the vehicle's tires. Proper installation can enhance grip and stability, allowing vehicles to navigate through difficult terrains more effectively. Many regions require the use of tire chains during heavy snowfall, especially in mountainous areas.
