If conditions are actually bad enough to need them, you should really question your need for being on the roads if at all avoidable...
+1 to this.
My town is on I70 at about 8000'. In the five years I've lived here I've yet to see a non-commercial vehicle with chains on. We also avoid the highway when the traction law is in effect if at all possible. Pretty much every time the traction law is in effect they will close the highway at some point as a preventive move or as reaction to wrecks. Not to mention that in those conditions you have to drive super slow. You are basically hoping you don't get caught up in the inevitable shutdown and if it's at night they will sometimes shut it down all night.
They do a really nice job keeping the roads cleared except during the height of a storm when they can't keep up. I get there's times when people need to be on the road then because it's happened to me on several occasions. Just make sure you have the right tires with appropriate tread depth, ideally all wheel drive or 4x4, and if not the chains or autosocks.
Also, be prepped to be stuck on the road for hours. Bring the appropriate clothes, water, food and make sure you're gassed up.
All that said you probably won't need any of it but it's better to be prepared than stuck out there.
