Autosocks
I have new 3 peak mountain snowflake AT tires on my four wheel drive F350, and am travelling to Utah the end of December. I carry a set of cable chains I've never used, and am considering picking up ...

Yosemite NP allows chains, cables, and tire socks, but not that sort of thing. I've watched many tests of different traction devices. My take is that chains are the best, and then tire socks and cables. One problem with those strap on devices is that while they work ok to get you moving and keep you going, they don't do as well to help you stop. While rotating, there will be times when the tire is in contact with the road surface and the traction device is not. Hit the brakes, and you just skid.
From the Yosemite NP web site:
Tire chains and cables are devices that improve traction in snow and ice. Chains provide better traction than cables, however cables are easier to install; both are acceptable under the law for most vehicles. Tire socks are also acceptable. Plastic devices, straps, and other emergency or alternative "tire chains" do not meet the legal requirement.
