No trim ring
Well, mine does (San Jose, Oct 65). I've read different reports about the Style Steel Wheel spare tire's trim ring - it does, it don't.
What was stressed was that only four Style Steel Wheels came with the car as an option, a Style Steel Wheel installed on the spare was another separate option. In my case, it was on the spare tire when I bought the car in 1996. By the way, it's the original spare - unused (note the sidewall - smooth, no ripples, an "800 XP"). However, either of the two previous owners may have put the trim ring on the spare. (It looks better with it anyway.)
