Because the tire is topographically a radially flattened torus, when you turn it half inside out, it becomes a 2D möbius strip. At this point it effectively has only one side. When you push such construct horizontally against a solid, because the z-axis perpendicular to the strip has no negative values (it only has one side), if that coincides with the orientation of the ∇Np of the solid, the z vector wraps around the solid. When the tire snaps to its rest state (inside in), it’s easy to see why it ends up around the pillar.
Honestly I’d just assume they cut them and use a torch to melt them back together. You’d probably never notice after a long enough time because of weathering and dust. Maybe even put there before it was capped off with the second floor?
Vulcanized rubber tends to burn more easily than it melts. You could melt them back togeather but you need finer temp control than a normal torch offers. Odds are they were just glued back togeather. It’s not like they’re being used on the road so you don’t need to worry about the glue holding up under those conditions. I’m also pretty sure I can see the line in the video where they were cut and glued.
How does turning then inside out solve the problem of getting them on the post? I can’t picture it in my head

This 3D animation demonstrates the concept:

Yeah that was another thought I had, I’ve seen them glue treads on surely glue would be just fine for this makeshift bumper system.
