This is a funny thread, use your handbrake....its fun. lol.
Helio, good tires make a big difference. I have michelin ltx m/s, they work great and have good siping. I wouldnt get chains, cables are much easier to deal with and by the time you need chains you are high centered anyway so it wont matter. Also wouldnt get blizzaks for your 4x4, it will eat them quickly. They have a different tread compound and work great but the weight of a 4x4 would just make em dissapear on one warm day.
