I'll just assume then that you understand the difference between set time and cure time. Gorilla Super Glue for instance isn't full strength for 24 hours. Many glues aren't fully cured for 72 hours. I don't understand why it's so impossible for you to believe that a cut can be glued shut on a tire with a whopping 90psi or less in it. I'm not gluing cords back together, I'm stopping cuts from getting any bigger. Cyanoacrylate adhesives work best on materials that are porous, but not too porous... you know, like rubber.
Then again, it would appear that those two pieces of rubber were attempted to be bonded by someone who doesn't understand how glue works. A chemical bond relies on being as absolutely thin as possible between the two surfaces to be bonded. That applies to any adhesive, between any substrates. I'm not fillet building, I'm gluing cuts. I use a single drop of glue, and most of it gets pushed out of the cut.
