for a good safe tire chain I'd go with spider spikes they're a bit pricey but well worth the money. I don't have them myself because of the tire that I'm running on my D but my buddy has them for his car and they're simple to put on the only down side is for a 31"x10.5 tire they cost 370 but you don't have to spend 30 mins putting chains on. these you put on a disc on the outside of your rim it attaches on the lug nuts. you put the disc on before you leave for the snow and then when you need chains you get out put this circle around your tire and lock it down and that it 2 to 5 mins and you're down with both tires. here's the web site http://www.spikes-spiders.com hope this helps I don't trust the regular chains just because you don't know when they'll break and cause some damage.
