Chains? Seriously? I think you're getting overexcited about snow.
Uhh you have never been over Donner Pass and seen the amount of snow it gets
But yeah anyways just use the thick black rubber bungie type straps and you will be fine. Actually if I were you I would test fit them one time just to be sure you know how to put them on the right way...it can get confusing when the snow is blowing and you are on the side of the road.
