I run these on my trucks:

We do a lot of railroad support work in the winter, keeping their dirt roads open into various locations. Lots of clay and caliche, which get slicker than snot when wet, add a little snow and no way will a truck get around without chains.
A few thoughts on my experiences:
1. Cheap chains break, resulting in body damage, broken brake lines, and getting stuck.
2. Dually chains are a PIA to put on, stick with singles for the rear if you have a dually. I usually run fronts first, then rears if needed, especially in ice and packed snow. Why? I like being able to steer.
3. It is advisable to put them on, if you know you are going to need them, BEFORE you need them. There is nothing funner than lying in 4" of mud topped with 12" of slushy snow or ice trying to get a set on. This is also done usually in the middle of the night, and/or in a blizzard. Carry a piece of carpet or vinyl mat with you. Lay out your chains on the mat, then drive up onto the chains. Or lay in the mud & snow, your choice.
4. Cable chains are a waste, as are light duty chains found at pep boys, autozone, checker, etc.
5. Chain sets with cam tighteners work great, but you still need to use bungees or the special tighteners to get them tight enough. Be carefull using bungees so that the hooks don't puncture your sidewalls.
6. Install them on your truck in good weather a few times so you know how and what to expect. Trim off excess chain so it doesn't smack your fenderwells or get tangled up in other components.
7. Carry repair links, cause if you break a cross chain on the outside, you'll have to fix it or take them off.
