I've no experience of winter tyres, apart from a hire car company in Russelheim apologizing for giving me a car without them on. Just how much difference do they make?
I can see how they could help, but other countries that mandate them usually have worse extremes of weather than us. I wonder if everyone had at least say 4 or 5mm of tread going into the winter if it would be a dramatic improvement anyway. Certainly my experience of getting new tyres mid winter was that 9 mm of tread gives you a staggering amount of grip compared to 2mm.
Brand new car less than a fortnight old E89 drove to Manchester for a flight to St Maarten from Glasgow and it was snowing in Manchester (February) kind of shoots down the 9mm tread thing!
Car was impossible to drive(had an SLK before so used to rear wheel snow shenanigans ) and by impossible I mean totally. Iturned of traction etc but car still kept stalling no matter how slowly I fed the power in. 19" wheels with 30,mm profile on rear probably didn't help.
