There are three types of wheelchair tires: solid, inflatable inner tube, and tubeless inflatable. The solid type walks faster on flat ground and is not easy to blast and is easy to push, but it vibrates greatly on uneven roads and is not easy to pull out when stuck in a groove the same width as the tire; with a pneumatic inner tube, it is more difficult to push and easy to puncture, but Vibration is smaller than that of a solid type; the tubeless inflatable type will not puncture because of the tubeless tube, and the interior is also inflated and comfortable to sit up, but it is more difficult to push than the solid type.
