Within the past two weeks there have been two separate sets of Bundt Cake rims which have been advertised as 15" (very rare and valuable, as you know) when they were actually the common 14", and both sellers claimed, when contacted by email, that they just hadn't bothered to measure when they posted the auctions. There are also a lot of wheels offered by people who measure the width over the outside of the flanges rather than between the beadseats and claim that this is the proper way to do it, in spite of the factory markings to the contrary.
