I use the Les Schwab heavy duty quick fits. They don't require much clearance, and are easy to put on, as long as you remember to hold the yellow with your left hand. I only chain the outer tires. I also use a set of "spider bungees". They keep things tight so you can effectively drive a little faster, and it negates the need to stop and re-tension, besides the initial re-tensioning after you roll forward 50-100 ft.
Chaining all fours requires a set of double-ladder chains, which are a bear to put on, and really only needed if you end up on un-plowed roads. Even when I was running wreckers on snow days, I never needed the doubles if I stayed on marked roads, plowed or not. I did however sometimes need front chains.
