If I lived where you live, I'd fit them without hestitation.
I don't. I live in the South West of England. Only this week has it even dipped below 10c during the day. There is no snow here - there almost never is. Even with the big weather warning for Friday, it stops short of where I live. So no, I wont be rushing out to buy a crappy set of steel wheels to join the winter tyre bandwagon that seeminingly only started rolling 4 years ago. And never once in 10 years have I ever had a moment where I thought 'I should change these tyres' so I'm certainly not going to blow a pile of cash and make my car look crap for 3 months of the year just to join the 'lets pretend we have a proper winter climate' bandwagon.
Your evo links are interesting. I suggest you read them yourself because these are interesting excerpts:
Braking from 50mph on wet, cold asphalt the summer tyre is dead last and 7m behind the best
That sounds terrible, doesn't it, the way they've potrayed it. But really 7 metres is the sort of distance you'd use to chose one tyre over another when buying but not to completely change a tyre type, downgrade your alloys and keep a spare set of wheels for, is it? More than 7m seperates the pack in performnace summer tyre tests, for example. And thats 7m between the BEST winter tyre and the summer tyre. It'll be less with the others.
Infact, last year there was a big wet braking test in non-winter conditions. It involved braking in the wet from a similar speed. Lets see what this horrendous 7 metre difference represents:
Eagle F1 Assymetric 2: 44 metres
Falken FK453: 49 metres
So it's only 2 metres more than the difference between an Eagle F1 and the Falkens half the internet bang on about it. And unlike the Falkens, which are pretty much always that much worse than an Eagle F1, the UHP summer tyre is only that bad when i gets really cold, during which time most sensible drivers are already taking it pretty easy..
But whats this? Some more data?

Interesting..
As you'd expect the summer tyre stops the shortest in the wet from 80kph, taking just 39.2 meters to stop
Continental WinterContact TS 850 stopped in 41.2 metres in the wet.
So really it's up for debate whether winter tyres even stop better in the wet - seems it depends on which test you read as to whether they do!
Lets read on.
but in the straight and curved aquaplane tests the wide-grooved summer tyre tops the tables
Fancy that.
Dry tests next..
As expected, the Continental summer tyre is fastest on the dry handling circuit and in dry braking. The margins, however, are not as big as you might expect - about 3 per cent over the next fastest on the circuit and about 10 per cent braking from 50mph.
But more importantly..
However, the feel of the winter and all-season tyres was noticeably inferior to the summer tyre….
There was a distinct wooliness and a general lack of precision and bite to the winter and all-season tyres compared to the summer tyre. Even the best of them (not an all-season, as you might expect, but the winter Michelin) significantly and obviously degraded the dynamic precision of the test car on a dry road.
Sounds great, doesn't it? What it shows is that its a real mixed bag and it's nothing like as clear cut as the 'Under 7c thats it, winters are loads better' that everyone seems to preach.
Basically, it tells us that:
a) In snow, summer tyres are crap. Winter tyres are far better
b) In the wet, summer tyres increase braking distance by a bit but are much better at aquaplane resistence
c) In the dry, summer tyres are noticeably superior and have dramatically better feel and poise
In summary then, winter tyres are something you fit only if you *NEED* them. You live in Norway. You need them. I live in Devon. I don't need them, I need a decent UHP tyre. Which is what I fit.
There is absolutely NO co-incidence to be found in the fact that before the couple of freak winters we had in 2009/2010, tyre companies didn't even bother marketing these tyres over here. Because they are for climates that are far more wintry than hours. When it snows in Norway, it is not the lead item on the evening news. Whereas it is in England, which shows you how much of a rare weather event it really is.
Go and tell somebody in Canada about how badly it snows here and they'll die laughing at you. Proper winter conditions, for which winter tyres are essential, involve snow which falls in November and finally gets lost again in April. Thaw in January is unheard of.
