Not the popular, preferred online consensus but is moot - when would you use them? In your backyard?! My concern is driving 50-100km per day over various alpine road surfaces with socks stretched over the tyres. I can't imagine how they'd last for long with a bit of inevitable 400hp wheelspin and two tonne downforce on crappy gravelly roads. Even if they provided the traction of chains or studded tyres I doubt they'd last a day, CBF changing socks all the time.
