On hard snowpack or ice, chains go on the BACK, or all four. If you brake hard with chains only on the front, the rears lock and slide while the fronts grip, and around you go back end first into the ditch. It happens a lot quicker than you might imagine!
In deep snow, it doesn't matter as much. If you let off the gas you'll stop moving forward pretty quickly. Off-road in deep snow, I use them on the front. On a well used trail, I keep them on the back.
