I think they cut them and reseal the rubber with glue
You can even see the seam in the video
But that´s 4 tires to cut and glue! Easier to cut and glue the one post…
They didn’t - the tyre was always there, the concrete post was erected within.
Pour concrete in column. Remove forms, and add tires before building next level?
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.
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.
Easy. Tires are just molded thick rubber. Just put 4 tire molds around the pillar and pour in melted rubber. Easy.
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 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.
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 🤔
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.
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.
That image just awakened memories from an internet (what seems like) ages ago
Pushing them through what exactly?
Yeah i am gonna need a video or at least a drawing before this makes any sense to me.
What does compressing it help to put it around the pillar? 🤔
why are people downvoting this amazing answer, lol
Pushing them through a solid concrete post? I don’t follow the physics?
Homie is an alien
Pushing them through what, the 4th dimension?
Yes this is how they do it. In some situations you can get away doing it diagonally but typically only works with type B tires.

With magnets and lasers, of course! One atom each time, it’s a real tiring process.
(I think that DASEIN is right, they erected the concrete post within the tires.)
Do you not know what magic is?
Well, when a post-daddy and a tire-mommy love each other very much, and the tire-mommy has a cuckquean fetish . . .
