I don't have a folding bike but I am making something with 16" wheels which I want the lightest possible everything on. I have some 16" tubeless-compatible carbon wheels weighing 300g and I want to get the lightest tire setup possible. I was thinking of trying the Schwalbe One tires at 173g but I am concerned they won't work well in ghetto tubeless mode. I have heard that the Marathons will work ghetto tubeless so I was also thinking of those, or the Continental Urbans ghetto tubeless.

Or maybe a lightweight tube is a better idea .. 83g looks to be a standard 16" tube weight. Maybe try the Turbolito latex tubes at 34g?? The tubeless sealant would weigh about that.
