Installing Tire Chains
Step #1 Practice before it snows. New chains sometimes need to be adjusted to the physical tire that you are using. To install snuggly, tire chains may need to have some excess chain cut off. You may need a couple of bungee cords to add some tension. It is best to know that, before you're snowed in.
Step #2 Lay the tire chains out on the floor with the curled ends of the cross chains down toward the floor.
The flat surface of the cross chains
should be against the tire sidewall when installed. Make sure that the side chains are straight and not twisted or crossed. Notice that there are 2 different clips/hooks at one end of both side chains.
The fixed hook will be installed on the inside (tractor) side of the tire.
The long, moveable clip 
will be on the outside side of the tire (away from tractor). You should now have the chains laid out in the fashion that they would wrap around the tire.
Step #3 Now the chains should be ready to install. Either drive the unit over the chains to a point that you can work them around the tire or jack the wheel off the ground. Make sure that you have read the disclaimer and practice safety first. Turn the engine off, use jack stands, etc.
Step #4 Hook the inside side-chain (AS SHOWN ABOVE). To start, just hook it to the first link of the other end of the same side chain that its on. Now hook the outer chain by passing the long shank thru the first link(AS SHOWN ABOVE) of the other end of the same side chain its on.
Then fold it back on itself.
Hook the hook into the chain. If there is a lot of slack in the chains hook, the hooks on both side to the next link in on the side chain etc.
