Tires are rarely out-of-round, as a piece of rubber can adapt. Bur rubber can be unevenly distributed, resulting on vibration and impossibility to balance, as an out-of-round wheel may be.

On the tires, we say that they have a flat spot.
I've heard that improper storage may also damage a tire, but I've never see this personnaly.

And, for the last part on wheels, BMW doesn't manufacture wheels themselves, outside company makes them on molds exclusive to BMW.
Ronal makes the 214, so they'll never replicate them to sell them directly.
But BBS could make a replica of the 214, but wouldn't copy another model they already have a binding contract with BMW.
