You need 6 chains which is what CalTrans calls max. 4 of your drives 2 on trailer. CalTrans is saying 80m is still closed but local news is saying open. If open you will be max chained from NV, CA border to Colfax

 

If a driver is using tire socks then boh drive axles and one trailer axle must be equipped with the devices. CA, in lighter snow conditions, has a version of chain law (I've heard it called "minimum chains" in which semi-trucks using steel link chains (conventional or old-style tire chains) may only be required to chain one of the drive axles. When using tire socks ANY chain requirement in CA is a "Max Chain" requirement, meaning both drive axles and one trailer axle must be "chained" with the tire socks.
