I run tires at lowest recommended psi on load and inflation chart on snow and ice.
Unless you are on a Big Scheduled Run With No Time To Spare, put your chains on, then wait and follow the plow truck :)
Use rubber bungee spiders on the chains. Run them tight. If you forgot to trim the long ends of the chains when you test fit them zip tie or wire them so they aren't flying.
Carry something to lay on in the slop when you are puttin on the jewelry.
Carry a stick with a hook on the end to reach the inside chain rail and pull it to where you can hook the inside without having to reach and soak your coat sleeve in the slop.
Don't speed. Take your time. Chains are hard on bodywork, brake wires and pipes, fender liners, mud flaps.
A set of light cable steer chains for your tow vehicle doesn't hurt. It's nice when the brakes are actually doing something on the down hill side.
I've never scared myself going up a hill. Down hill on ice/snow/mud when chains should have been on is another story...
