A couple of other things.
Do not run them on dry roads.... not trying to sound stupid.... but it does need to be said..... just like 4x4.... only run them if you need it....
Watch your speed..... Yes, because it's slick if you are using chains, but, centrifugal force will pull the cross chains away from the tire, like a jump rope. So it's IMPERATIVE to install them correctly, and as tight as possible. For me, on the tractors, I deflate the tire, install the chains as snug as I can, and them re-inflate the tire to proper pressure ~12lbs. This makes them fairly tight and limits the "flail" the chains have. As you can see, I have very limited clearance, and it's not uncommon to see the rear fenders damaged due to chain flail
Practice installing them several times, at home in the driveway. Chains are not necessarily difficult to install, but I would not want to try installing them on the shoulder of a road. I've read of people make the comment on the Cub forum make the comment it only took me an hour to get the chains installed this time. Now, this is the second or third time of installing them. Myself on the other hand, I can take the decks off, install the blade, thrower and both sets of chains in an hour. But, I've done the swap/install probably a hundred times in the last 40 years. They make tire chain install ramp, that allows the chains to lay in grooves, so they can move, but are placed under the tire. I normally have the tire off the ground, and "roll" them onto the tire, but that is different getting ready for winter in October, vs on the side of the road.
When you get them, remove them from their container, and make sure they are straight. Meaning, look like a ladder lying on the floor. The set of chains I got with one of my tractors had just been in a pile. It took me almost an hour to straighten out both chains so they could be installed. All the cross links on the same side of the cross chain, and the side chains lying straight. The chains can "pass through" between 2 cross links, and become tangled. This also makes them shorter....... When I store mine, they get removed from the tire, and I immediately hang them on 2 nails on the wall of the garage and let them hang until I need them again..... They NEVER get put down, the only thing they touch is the tire, and the 2 nails........
If you take care of them, chains can last a very long time. The set of chains on the tractor with the snow thrower were purchased new in 78 or 79 and have been used every winter and also for several years in the fall when we would plow the garden. They are not perfect, and have had a couple of repairs, but they still do their job and help me remove the snow.
