In the Ukraine if there is snow on the roads or it is icy you can get fined if not running winter tyres. It is very, very rare for there not to be snow and icy roads at various points during the winter. Recently it has been unusually warm for the time of year with it up to +7degC. When I ask my wife what the weather is at this time of year, if she says warm that means anything above -5degC and cold is anything below -10degC.
To show the difference between the UK and the Ukraine, if we have snow and a bit of cold weather then there is a big fuss on how dangerous it is. When there were the recent protests in Kiev on the EU agreement, there was plenty of snow on the ground and the temperatures were -10degC or below and many were protesting 24/7 and camping in the main square. They just take cold weather, snow and ice, in their stride, but unlike the UK, they do dress appropriately.
I can see the EU bringing a similar law in for all EU countries as it is a good earner for the tyre and wheel companies plus the extra storage fees. You only have to look at the herbal remedies market and their attempted ban on all non-manufacturer car parts to which side of the
brown envelope fence they sit on.
Winter tyres like everything else have their place, but would be rarely need in the south of England, except in Reading where the terrain is like a billiard table, but they they need them for the man made hills with the bridges over the motorways, so they should be compulsory from September to March.
