Should Snow Chains Be Installed on the Front or Rear Wheels of a Front-Wheel Drive Vehicle?

For front-wheel drive vehicles, snow chains should be installed on the front wheels. For rear-wheel drive or four-wheel drive vehicles, snow chains should be installed on all four wheels. The installation method for snow chains is as follows: Lay the snow chain flat and centered in front of the tire. Drive the vehicle forward half the length of the snow chain so that the tire's contact point is at the center of the chain. Fasten the hooks on the inner side of the tire first, then secure the hooks on the outer side. Continue moving the vehicle forward to adjust the connection points under load and ensure the snow chains are firmly fixed. Principle of snow chains: They introduce a medium with a higher friction coefficient between the road surface and the tire. While enhancing the tire's grip on the ground, the adhesion coefficient between the tire and the snow chain also increases, thereby boosting the friction between the vehicle (i.e., the tire) and the road surface. This is because the snow chain concentrates the vehicle's weight onto one or several points, increasing pressure and consequently friction. Snow chains are typically used on icy, snowy, or muddy roads.
I recently helped a neighbor with this issue. For front-wheel-drive vehicles, snow chains should definitely be installed on the front wheels first. The front wheels are the driving wheels responsible for pulling the vehicle forward. If they slip on ice or snow, the entire car can lose control. Installing chains on the rear wheels is ineffective since they merely follow along as auxiliary components. I recommend first checking if the front tire pressure is normal, as pressure that's too low can also affect anti-slip performance. When installing, park the car on level ground, spread out the chains, align them with the tires, and slowly fit them on. Secure them tightly with hooks, then drive a short distance and check again to ensure the chains haven't loosened. Remember not to drive too fast with chains—speeds over 50 km/h can easily cause the chains to break and damage the tires. If you're traveling long distances on snowy or icy roads, it's safer to install chains on all four wheels.
I often drive on mountain roads and snowy terrain, so snow chains must be installed on the front wheels of a front-wheel-drive vehicle. The front wheels handle both steering and power delivery—if they slip, the car won't turn properly. Once, I took a shortcut and only installed chains on the rear wheels. While going downhill, the rear end kept sliding, nearly causing me to hit a tree. It only stabilized after I added chains to the front wheels. When installing them, it's best to wear gloves to prevent frostbite. Don’t fit the chains too tight or too loose; leave about a finger-width gap. If the rear tires are severely worn, they should also be checked, but they aren’t the priority. Before winter trips, always check the brake fluid to ensure it maintains low-temperature fluidity. Keep a shovel in the car for emergencies—it could save you if you get stuck in the snow.
