Some time ago I came across this unique video. "Feel the Sensation of the Tire Without Air", It turned out that it was a video about the TNI AD's innovation in making tires without air. So it's not like tires in general, when viewed from the side this tire has holes forming a wide nest pattern.
A few years ago the American military made tires without air too. It seems that the Indonesian military also wants to make the same discovery. In 2017 the initial prototype was successfully made, but when it was tested it failed, this is because the technology they use is still very simple.
From year to year they continue to perfect it until now, they seem to have succeeded in making a successful prototype. Why is this important? because ordinary tires are vulnerable to attack. This tire is able to withstand bullets and sharp objects.
But of course this tire is still in prototype form, it needs more in-depth research if this tire is to be mass produced and used for civilians.
