I'm amazed that the government don't legislate to be honest. Compulsory Winter tyres would save a fortune in gritting costs alone. Plus they would save all the costs of fixing the damage that salt does to the roads. Obviously they would still need to plough to keep the roads passable.
The great cost would be transferred from the local councils/ government onto the good old driving public cash cow.
Plus the big tyre companies would love them to legislate.
I can't understand why they haven't already enacted the law, quoting the EEC to pass any blame to.
