... is anyone aware of where to get, specifically, a matching spare wheel/tire? preferrably a grey matching one, and definitely the same size tire. Any thoughts or ideas 'Doo'er's!?
Well, if you want it to perfectly match, then either you need to do a lot of looking around to find what all is offered and to get what you want, or go back to the dealer as they should carry what you need.
Personally, I don't think it matters since the odd-ball wheel is to be used as a spare and will have limited road time anyway. I can see wanting to keep the tire sizes comparible, but the look of the wheel is very minor (IMO).
Northern Tools carries a fairly wide selection of trailer wheels and tires; might be good to give them a try (either in store or online). Academy will also have some to choose from (if you have these stores near you, they are big in the South).
I found my spare for $10 on Craigslist. Wheel is a close (but not perfect) match, but needed a little clean up. The tire is the same size and was in good condition. A little paint on the wheel and most people never even notice the differences in it. Besides, like I said, it sees very little use (I haven't used it yet).
I know this isn't an exact answer to your questions, but it does provide a few things to, at least, think about in making your choices.
