I wouldn't run any steels even in the winter. Alloys are cheap these days.
However, I would not run Detroits or any other clear coated wheel in the
winter though. 1. Clear coat is not as resistant to stone chips. Earlier or
later this will cause some damage, and salt will do the rest. 2. It is a pain
to repair clear coted will, as you first will have to turn the wheel on a lathe
before repainting for a like-new finish. Regular painted wheels aren't any
issue at all. Just visit a paint shop.
Recently the law was changed to make the fitting of winter or "all-weather" tyres during the winter months (even for foreign visitors) compulsory on safety grounds with hefty penalties for non compliance.
No big deal at all. Guess it's just 10 €, and even just hyothetically, as no
police will ever look after your tires as long as you don't have an accident.
Admittedly, more people run dedicated winters since, which without any
doubt is good.. :wink:
Before, one idiot on summers was enough, to stop the whole traffic.
