You all have inspired me. I just ordered the two-linked ladder chains for both front & rear tires from tirechains.com. The ladder chains were all that came in my tire size, but 2-link design looks sufficient, since I will be using them for paved applications. I just don't want to slide down my curved drive: 60ft drop over 300ft and a pretty steep drop-off if I go off the driveway. Now as to chains front & back, I say YES!! I need steering more than 4 wheel drive traction. I am less worried about going up the hill than sliding down it. So, chains front & rear and 2-wheel drive, until I get stuck.
Last winter, on one ocassion it took me fifteen minutes to inch by inch SLIDE my truck down the driveway, but it didn't take any time to drive it back up, since I left at the bottom of the hill, where the roads are salted and paved by the county.
