It's fine to have doubted me, because until I saw one in person I even doubted the people who had told me about them.
I can't see a really good reason for them, other than the reason I explained above. I don't know why you would want a whole set of them, front and rear...
That said, if there were actually some made with the small 10 lug pattern I would not mind a set for my truck. I would only want them to be different though, as I already have a good set of 22.5 wheels. If I had a set of the adapters I would run the same size tires, the only difference would be the aggravation of getting the rims to run true, and the looks.
