Where to find information about chaining up in each state?

Make sure you have 8 chains for Washington..they require 2 spares.

 

The state Department of Transportation for the state, it has a different name in every state.
Oregon has the best graphic display of their chaining requirement. If you make Oregon happy, you will be legal in most other states. Some states don't allow chains on their roads, IIRC. Some states don't produce anything for guidance.

If you never plan on driving in ice and snow meaning your plan is to park, but you have to carry something to be legal, like in OR and WA Oct 1 through April (IIRC) and a few states you have to carry chains (or alternative traction devices) I would carry tire socks. They are light and legal. If you are planning on driving on chain-equipped tires get chains, not tire socks. Tire socks are not durable and it is easy to wear them out in one trip unless the road is fully snow covered. In non snow covered surface will wear the socks down very quickly. If the socks are not installed properly or you drive faster than 20 mph you will throw them off the tire. If you spin a wheel while "wearing" socks you will either throw the socks off the wheel or wrap them around the hub between your dual tires. Socks cost the same as chains. They are easier to install but they come off easily and it takes time to dry out.

Really, aside from California, Oregon and Washington, most states leave it up to you. Some states even ban chains, and others at least limit when you can use them. I think the last time I saw a truck driver hanging iron east of the Mississippi was one extremely snowy night on routes 7&9, before this BIG hill bringing you from Vermont to New York; he was a western driver, so he had chains and he used them. That night, a LOT of trucks broke traction before they hit the summit, but he managed to get through.

 

Since we're on the subject of tire chains, I have 4 brand new bags that I swear I ain't ever gonna use. If any of you need them and find yourselves in the Iuka, MS - Florence, AL or Adamsville, TN area, I'm willing to let them go for around half price.

I also have a veritable **** load of used chains, including a set of 3-rail, that I'd part with for 50/set.

The only keys I have are in the new bags, though.
