Just a bit of a summary on this , and after reading the other thread it seems all over the place.
Summer tyres - you will no doubt survive but if you come across a hill or other people stuck most likely you will be too , the further south you are the more likely you are to rely on them unless where you live is fairly rural.
Snow socks - used sparingly they will get you out of trouble with summer tyres on .
Chains , there is a myth that chains don't work on low profile tyres or lowered cars , while for traditional chains thats true there are chains that are designed for alloy wheels with low profile tyres etc , mine fit on our lowered clio no problem , and our 18" 40 profile audi . Maggi Trak sport are what we have
Winter tyres , have been used to them in germany i can recomend them , they won't get you out of anything , but are huge amounts better ,combine them with some sport chains in the boot and you will get out of most situations
Studs , if we have months of a deep freeze and run out of road salt then these are the ultimate , you can legally use them in the UK but being honest why would you own a set ?
