That's dumb. But they're probably just trying to cover their azz. I you just have wheels that you need tires mounted on them, just bring them in and say their off an older one or off a trailer. Just make something up that doesn't require them.
I've had to do that when I wanted crappy tires I got from the dump mounted on crusty old wheels, just said they're for an off road farm trailer.
