Well the thread starter mentioned that he works as a gritter, which means if called upon, it's likely to be over lots of snow on the road...whereas the Crossclimates (summer biased all season, or is it a full summer with snow abilities?) are movable on snow...a proper winter would setup or Weatherproof (winter biased all season) would be better. Where in the UK has this much snow? Up north maybe? Else I don't know. I know a friend from Russia where winters are...well...very cold and snowy, even a full winter tyre don't cut it, most run studded winter tyres. Else snow socks or chains if stuck...
Well, in the same way - I spotted a Suzuki softroader(not a full blown one like Jimny) today in a supermarket carpark, what "stuck out" was it was fitted with off-road tyres, ie tyres with rough cleats, good for gripping on exposed stone rocks - as handy as summer tyres in winter conditions.
As I have said many times, and I'm not the only person to know this, with an ordinary car with minimal ground clearance, if driving on an unploughed road after a heavy snow fall, the main
problem will not be grip, but the snow lifting the car wheels up of the compacted snow in the wheel tracks - so having tyres that will give best grip in UK winter conditions is the only smart buy, ie either allseasons for using 12 months a year but not being optimised for winter use, or winter tyres for using 4,5 or 6 months a year. Proper winter tyres let you do more than just move away and up slopping areas, they will also give you extra grip to steer and stop - and that means a lot more than just being able to move away without having just grip to steer and stop!
