I made a set of
truck chains for my Samurai , and asked the Maine State Police about running them on the road. They said tire chains are legal to run on all roads in Maine and are treated as studded tires, thus they have the same time restriction. I frequent my woodlot, used to enjoy four wheeling occasionally, and would be completely
stuck without chains in the winter, even though I have a winch on the front and some of the most aggressive tires on the planet (Swampers). A hand winch, which I also have, is a "
comealong", and quite frequently its limitation is the 30' or so of cable it has attached to it.
I have cables for the minivan, which has just all-season tires but is all wheel drive, and snow tires for the Trooper. I have not needed to use the the cables, but they're there just in case. The comealong travels with whatever vehicle I'm taking in the winter, and I usually carry my recovery bag, which has 100' of 3/8 cable, 60' of snap straps, clevis', tree straps, and small shovel. I have had to put chains on while stuck and although it can take some time, it's certainly do-able. A number of years ago I slid my BMW off into a ditch and had to put them on. Despite the glare ice the car backed out of the ditch without hardly slipping a tire.
One of the most useful things I have, despite all the rest of my recovery gear, is a pair of
raised steel expanded metal grates . They're 12"x30", about 1/4" thick, and double in the summer as campfire grates. They're quite heavy duty, easy to move around, and most of the time allow just enough momentum to get unstuck.
I would keep chains in the car, just in case, along with the usual winter survival gear, which I leave in a duffle.
I have used studs on many tires, and while they may help some, their scratching on ice isn't enough to get you out of a hole if you're stuck. I akin it to having long fingernails while rock climbing. I do not doubt that they help some, but would not only rely on them when on a backroad.
