I've got some "Les Shwab" quick fit diamond chains for my suby. while these are more expensive (about $60) than the regular cable chains you can get at any auto parts store they are far superior. they go on easy, even when digging out, and provide way more traction. And since theyre beefier you won't pull a swage off when you try and drive out after a cold day and they've frozen to the ground. a real danger with cheaper cable chains. hope that helps. I don't know if there is a Les Schwab dealer here in Bozeman it's worth looking into.
