I also must ask why? You won't need them between Denver and SLC. If the road is open, you can make it w/o chains. Now, as you near OR, and wetter snows, that might be a dif story. You are not in a rush, so, don't push it.

If you really need em, get cables, that is what the CSP uses.

I've never needed chains on the freeway....except on Donner pass, when it wasn't snowing that hard. But, that was because Californians can't drive in the snow.
