When I was last in Germany checking out the 2nd hand cars, every single one, without exception had a set of winter wheels and tyres strapped in the boot.
For those interested its what the 'lashing points' in the boot are actually there for.
I believe its the law to use winter tyres in Germany and in some other countries.
However, my point is that all the wheels in those German VWs without exception, were the basic steel rims, not one of the 200 or more used cars on show had alloys rims for the winter tyres.
As another word of caution I have seen an alloy wheel, fitted to a working Range Rover, strip the spokes from the tyre rim when it was bogged down when the driver was over zelous with the throttle.
