I'm not crazy, the attack has begun.
Funny you say that, when I bought my winter tyres, there were alloys cheaper than steels! In black too, so figured show dirt less, and black alloys on the dark grey Ampera look very nice, IMHO. I hope @Garry TheBiz might agree!!That is why I fit the winter tyres on cheap German steel wheels when the weather gets bad . . .
