PTU tubes V traditional tubes.

[gavroche]

Do you pump up ptu tubes with the same pressure as normal tubes?
I mostly use rubber tubes at 100 psi.
I also carry a ptu tube in my bag but have not used one yet as I am very lucky to have very few punctures.

I'm assuming you mean TPU tubes, personally haven't used tubes for a long time although I do carry a spare standard rubber tube on long or multi day rides, usually end up giving to other people.
