What is the base vehicle for the Concorde? A dealer would know which chains to get.
I'm very convinced in favour of true snow tyres - they are exceptional. I have been on 10cm pure ice and also hard packed shiny snow. Wide open flat camp site so I tried a few emergency stops at about 20mph - the truck stopped quickly and securely.
All mine are steel wheels - I have 4 extra wheels and swap over tyres twice a year.
I also bought mercedes heavy duty chains from Innsbruck main dealer, but have yet to need them.
Once you have travelled to the alps in winter a couple of times, you realise they take snow in their stride. Busses keep running, bread is still delivered.
I too change the wheels on both of our cars to fit winter tyres in the winter season. As you say, they make a tremendous difference.
Most people associate winter tyres with snow and convince themselves that they are not warranted in the UK. What is commonly referred to as winter tyres (and sometimes even snow tyres) would be more appropriately labelled “cold weather” tyres. Winter tyres will out perform summer/all season tyres in temperatures of 7 C or below. My view is that for many people who have an early morning commute and evening return that the temperature through the winter months would, more often than not, be in the temperature range where winter tyres would be preferable.
In your post above, were you referring to winter tyres or snow tyres. If the latter, how do they differ from winter tyres?
