I think they cut them and reseal the rubber with glue

You can even see the seam in the video
But thatΒ΄s 4 tires to cut and glue! Easier to cut and glue the one post...
This is done by turning the tires inside-out and pushing them through horizontally. You need a machine to do it though because that rubber is very stiff.
How does turning then inside out solve the problem of getting them on the post? I can't picture it in my head
Because the tire is topographically a radially flattened torus, when you turn it half inside out, it becomes a 2D mΓΆbius 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 βNp 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.
This 3D animation demonstrates the concept:

Very enlightening response, thanks!
That doesn't make sense to me either
Either there is a seam in the tires, or the post...or the tires were put on while the post was built. I'm stumped π€
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.
why are people downvoting this amazing answer, lol
Well, when a post-daddy and a tire-mommy love each other very much, and the tire-mommy has a cuckquean fetish . . .
They didn't - the tyre was always there, the concrete post was erected within.
Easy. Tires are just molded thick rubber. Just put 4 tire molds around the pillar and pour in melted rubber. Easy.
It's not a load bearing post. The blue signs can be removed to show the gap. It hasn't been a load bearing post since someone crashed into it.
Pour concrete in column. Remove forms, and add tires before building next level?
Just a guess... the tires are cut so they can be placed around the post. Perhaps there is a latch attached to either side of the cut that can be engaged to hold the cut together after it's installed.
