It’s always nice to use a product that manages to reimagine a product category and surpasses it.
WA state finally made Autosocks legal in 2012 and my wife and I were the first in line to get these. You can put them on in seconds with no effort, tightening, retightening etc needed. They work just as well as chains. You can plough through the snow. They have no metal on them. So no damage to the tires or to the roads. Been using these for two years now – there’s no real catch except you gotta take them off when there’s no snow – the hard dry road will do a number on them. But you shouldn’t be driving on dry road with any traction devices anyway.
I highly recommend the Autosock. Get them here (do check the tire size to get the right fit).
