I don't like chains. I carry a set for the rear axle, we do have 4 x 4 which makes a big difference. We have not used the chains for maybe 10 years, and that is fine with me.
In bad weather, there are two overwhelming issues that must be considered, visibility and the other vehicles. The road may be clogged with stuck vehicles and just because you can move does not mean that there is any place you can go. Just one truck across a two lanes in the middle of nowhere and its time to so something else.
Classic case a spring storm on 285 south of Cumo Colorado, the road was snow packed, some blowing snow, visibility maybe 1/4 mile, not much traffic, but a small semi lost it on the first curve/downgrade south of Como. The road was blocked. If you know the area, there are not a lot of options. We returned to Arapahoe Hills.
