I wouldn't recommend the Autosock, or whatever they're called. Today was the first decent bit of snow we've had. By mid morning I had counted about 5 of these things that had deserted the car they were supposed to be helping, left on the carriageway. Not a cheap thing to lose.
Last year I used chains and they were great, fitted in a couple of minutes and very stable in the snow.
The problem with both the above is that they are great for the conditions they were designed for, and cr4p at everything else. The guy who was driving down the hard shoulder this morning will testify. The road was clear and he was using the Autosock things and was looking for snow!!!
This year I've bought snow tyres. They're not that much more expensive than normal tyres and are great throughout the winter, not just in snow. Pulled up the hill to get home this morning without spinning, no need to get cold and wet playing with chains. For the average snow conditions they are worth it. I still carry chains just incase there is too much snow, but I don't think that'll be a problem.
I had some years ago on a Mk11 Escort and was the only car to get out of our valley during the snow.
Maybe worth getting a second set of wheels so you don't have to pi55Around changing tyres at the end of the season.
Can one person fit those Autosocks on their own?
