I have a full set of 6 plus 2 spare (8 total) Auto Socks size AL79 for tractor and trailer for sale. Asking $500 for the set which sell new for around $900 depending on where you shop. They also sell these at TA/Petro, but you'll pay even more than retail there. If you don't like my price, make me an offer I can't refuse.
These are brand new never used still in the sealed packages. If you frequently chain up in snow conditions, I DO NOT recommend getting these as they do not hold up under frequent use. But on the other hand if you don't chain up but need to carry chains to be legal, these are legal in all 50 states, and if you absolutely do have to use them, they do work great in snow. Not so much on ice or dry pavement which destroys them quickly. Each package of 2 socks only weighs 4 pounds, so they are light and much easier to store than bags of steel chains. I only ran the west coast and never chained up, but carried them to be legal wherever I went. There are many videos on YouTube which show how fast and easy these things are to install and take off. Much easier than steel chains.
Shipping these will cost me around $100, so I'll split it with the new buyer and charge $50 for shipping and insurance.
