Grande-
Two comments (disagreements) with what has been said.
First, chains don't belong on the front tires of a 4wd vehicle, so the experts tell me. I have talked with many equipment people from all over the mountain west and every one agrees that doing so will throw the fwd ratio out and can do damage. Many change the front tires with half use wear to avoid ratio damage. My suggestion is don't take my word but talk to some people knowledgable in this area.
The second area is in how to mount snow chains. The first 40 years of my adult life was to do it the good old fashioned way known as snow chain wrestling, as virtually everyone here has described in this thread. Then being up here in the state of North Idaho along the Canadian border I learned how to mount chains in one minute per tire without effort on my F250
truck and slightly longer on my F350 with duallies. This same method is employed by ten wheelers, tractors, and skid steers.
The chains are laid on top of the tires (you can do both tires at the same time) with the chain link ends (sharp points) away from the tire as the chain lays on the tires so as to hit the ice and snow as the tire turns. The chain "s" hook is on the inside of the tire and the chain through latch is on the outside wall of the tire. The chain lap over on the side walls are even down the inside and outside walls.
The "s" hook/ latch end of the chain should touch the ground at the front of the tire and be tucked under the tire as near to 6 o'clock as possible and with the chain spread so the hooks clear each side of the tire. Do both rear tires as described before moving your vehicle forward.
Drive your vehicle a foot or so forward so the latching ends are at about the 5 o'clock position. The hook to/latch to ends will be hanging loose and the chain is completely supported by the tire. You simply hook the two inside links and then the
outside links and your chains are ready for the tensioners.The chains tensioners rarely ever need tightening after being set.
The total lift of chains after you place the chains over the tires and drive forward is to lift the few inches of bottom chain to connect to the rest of the chain. Many of us up here chain up and chain down four or five times a day.
If you chain up and down regularly a good tool for dark is to have a snake light to put around your neck to free up both hands and a small canvas piece to place on the snow.
I would like to lay claim to this simple effortless process but others showed me and its used up here and in Russia.
You can probably chain up faster than you can read all this.
Hope it makes sense and helps.
