Why predictable? Mine's simply a statement of what happened 22yrs ago in West Germany. I didn't know many people, English or German, who changed tyres - chains were used in extremes, but wheel rims were a tad different then. Germany is a big place and experiences more extremes more often than we do. Is there some reason why you believe you have superior knowledge and experience?
Perhaps because Germany isn't surrounded by water, sees much lower temperatures and a lot more snow? We haven't had any snow for about 2 years, other than a pitiful dusting that's all melted by 8am. Which is precisely why winter tyres are an expensive waste of money. Besides, contrary to popular opinion, the Germans really aren't right about everything.
I think you'd have to catch them on a really good day, or be a doris in a short skirt, before they'd do that for you.
Probably because winter tyres weren't a legal requirement 22 years ago. They are now and for very good reason. People seem very confused that Winter tyres are just tyres for alpine snow conditions. Very wrong, have a look yourself. They tested stopping distances in moderately icy conditions and the contrast was night and day. Similar results achieved in the wet. We may not have ice and snow like other parts of Europe, but we do have a shed load of rain and standing water. It's not my superior knowledge it's research bodies across Europe that have conducted tests that have resulted in making Winter tyres a legal requirement. They haven't done it on a whim.
Find me a single test where a winter tyre beats an equal quality summer tyre in the wet or dry at any temperature then. Just one will do.
An actual real world test, not an article with a picture made from somebody else's unmentioned statistics.
