I got a set last year, and I wouldn’t hesistate to get another pair.
Had to use them once in anger one night last year, after taking a back road I really shouldn’t of, and having to stop in the middle of a snow drift (when I hit the drift, it sent the snow up and over the car, so I didn’t have a clue where I was going, so had to stop)
Hardest bit was clearing enough snow with the shovel so I could get the car moving enough to get them on, by which point my hands were like ice, so I then had to sit in the car for 5 minutes to regain some feeling to get the snow socks over the wheels. Even once I got one on, I had to have another warm up before getting the other side on, (the fact I was stuck on the corner of a valley with the wind blowing straight up it really didn’t help!).
I’ll admit they weren’t the easiest of things to put on, but that’s because there’s not much room between the tyre and wheel arch on my car, and the wheel arch also had a good build up of snow, which made it pretty hard to get the sock hooked over the tyre.
However once they were on, the car just kept plodding on through the snow. I was amazed at just how effective they were. I could hear the car underside sliding over the snow at times, but it just kept going.
Almost got stuck with them a couple of times, but a bit reversing and a bit more forward momentum got me through.
Kept them on until I got back down to where the snow was only a couple inches deep, and took them of. One side had gotten a couple tears in it, but was due to whoever made the first tracks over the exposed bit road hadn’t stayed on the road, and had gone along the edge of it instead, which the sock had caught on a few times.
After last weekends snow, they’re now back tucked behind the seat, along with the shovel, just in case. I’m not planning on having to use them again, but they’re there!
