I'm the wrong side of 50 to be fannying around with one tyre then another.
in any case, I learned to drive in thick snow - the wing mirrors were grazing the top of the snow! (in the days when wing mirrors were attached to the wings). I managed to get up the hills in the Pennines on whatever rubber happened to be on the wheels & I've yet to have a problem getting around.
Although, I have to admit to having a pair of snowsocks in the boot - just in case.
That said, when it has snowed, I spend a couple of minutes fitting the snow socks because it is simply so much easier to drive with them on.
£40 investment back in 2007 still working well. Bargain
Edit : just noticed one of the poll options - "Already have some, used them for years" - doesn't rubber deteriorate/perish over time? Isn't there a danger of being lulled into a false sense of security?
