On technical note, at least Caltrans makes chain requirements several miles before you see snow on the road.
In the past I drove 7 tons ClassA over Sierra. The chain restrictions covered 12 miles, while only about 5 had real show.
Chains on only one side of duallies wear out on that single drive, so while camping on other side I had to replace few broken links.
Than on the way back chain restrictions again, so I put the chains on other side and after another 12 miles the chains were no longer useable.
When with chains going over 25 mph gets pretty risky and uncomfortable, with cables 40 mph is fine.
