I've seen a different sort of bike tire in China - there's a bit of an explosion of hire bikes going on in China, and if you have millions of bikes in the field the last thing you want to do is to have to deal with tens of thousands of daily flats
Have a look at the tire on the orange bike in the front in the photo below (or the light blue one about 8 bikes back) .... it's full of holes, the rest is solid. It's different from the designs above, I'm told it rides like a traditional tire
