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.
Bryan is correct.
The Les Schwab chains are designed for less vibration. There is a chain row running up the middle on every other loop over the tire. Oregon and many other western states require you to "carry" tire chains that will fit. If towing, you are required to put chains on the rear driver axle and also the towed rig. The state police do patrol and if (god forbid) you got in an accident and chains were required it wouldn't be good for the wallet.

With dully's, you can drive up on a 2 x 6 and strap on the chains to the outside tires.
