We do not use chains too often here during the winter in Interior Alaska....
The majority of set ups I have seen for residents living up in the foothills with 4WD - configure them with "chains" on the rear (outside rear with duallys), along with a smaller "cable" assembly installed on one of the front tires for steering traction purposes...
The winter elements here in my area for example in the valleys are much colder temps, compared to the foothills in which 200 feet or higher over the valley tends to be much warmer during the winter, as it is quite common to be driving up a hill climbing 200 to 500 feet higher in elevation where it would be anywhere between 10 to 30 degrees F warmer versus the valley you just driven out of 5 to 10 minutes ago.
When the elements are right, someone would leave a valley at -5 below F with slick roads that are drivable with no chains, and commute home up a foothill as the temps have increased - now hovering around +20 to +30 degrees F with even more slick road surfaces to deal with, as the frozen road surfaces underneath are now trying to thaw and therefore you have warm icy roads equivalent to driving on oil, and that is no fun when you are climbing on a decent grade of a hill without any steering control, which is why either one or both front driving wheels are cabled or chained up at that moment, or if already set up with tire chains a handful of people prefer one cable assembly over one of the front wheels so that they can have steering control, which makes a world of difference.
We just had a major two day storm (15 hours without power for me), with drizzle rain, 70 mph winds and variable warmer winter temps in between making roads havoc, this is one of the times residents living up in the foothills had to chain up in some areas.
