Here is a step-by-step guide on how to install car chains:
1. Park your vehicle in a safe location. If possible, park on a level surface and make sure the parking brake is engaged.
2. Remove any hubcaps or covers that may obstruct the installation of the car chains.
3. Lay the car chains out on the ground in a "U" shape, with the open end of the "U" facing towards the front of the vehicle.
4. Drive the vehicle forward until the front tires are centered in the "U" shape of the chains.
5. Get out of the vehicle and carefully drape the chains over the front tires, making sure that the chains are centered on the tires.
6. Fasten the car chains according to the manufacturer's instructions. Some chains may have hooks, buckles, or other types of fasteners.
7. Repeat steps 4-6 for the rear tires, if necessary.
8. Drive slowly and carefully to a safe location. Avoid sharp turns and sudden braking.
Car chains should only be used when driving in snowy or icy conditions. They should be removed when the roads are clear, as they can damage the tires and the road surface.
