But in the UK, why would you have winter tyres over decent regular ones when most of the time either the snow is so deep it is not sensible or possible to drive regardless of tyre choice or their is no snow settled / roads are grit etc?
This winter tyre craze has only become more prevelant since last year. The population have been carrying on using their normal tyres right throuh the winter for years and years
Because on many mornings there will be icy roads, grip at lower temperatures is higher with winter tyres on wet AND dry, and the colder it gets, that improves exponentially as the summer rubber just gets harder and harder.
Average UK temperature between end October and end February is below 7 degrees, hence why many want to switch for the safety margin.
Sure winter tyres have become more in focus again since last year because in snow, they are clear winners, in other conditions the difference is not so great, but great enough to justify using them if you are gonna be doing many miles in that period.
Many people thought smoking was healthy in this country until the science came along to disprove that assumption. Many people did not drive cars with advanced traction control systems which are now on almost every car. A traction control system that finds you losing front grip will cut the accelerator and maybe even apply the brakes, forcing you into a LOOS if you just have front winter tyres.
I am sure in parts of Scotland, winter tyres have been far more prevalant than down south, just like they are in Europe. Because we are now experiencing far worse condition winters, they are becoming more talked about in the south as well.
