Q: Does anyone have any experience with a puncture with these tires? Did they work?

Yeah, I bought these in January and both of them were brought down by holes smaller than a pin hole. Don't waste your time on these.

Q: What's the Psi for the inner tube

PSI is on the tire not the tube. Probably 20 to 30.

Q: In case of a large puncture can these tubes be patched in the normal way?

I don't know, but I would think you could patch them. The tubes look and feel like a normal tube.
