To the best of my knowledge they are OEM. The one with the Goodyear tire was on my 4Runner when I bought it and looked like it had been there for years and years. The one with the Goodrich tire was a throw in from the seller when I bought a set of Toyota alloys. They both have the 16JJ markings on them but after that the markings/numbers are different.
I got a Craigslist e mail of interest last night so we'll see how that pans out today.
