The invention relates to an inflating-free pneumatic tire. A main body of the inflating-free pneumatic tire consists of a crown and a bead toe which are connected into a whole, wherein the crown comprises a carcass and a wear-resistant layer; an embedded clamping strip is arranged on the bead toe; five buffer air cavities are formed inside the carcass; a left limiting groove and a right limiting groove are externally formed in the joint of the bead toe and the carcass, and a left rectangular buffer air cavity and a right rectangular buffer air cavity are internally formed in the joint of the bead toe and the carcass; the interval between cavity walls of each buffer air cavity is the same; during working, an elastic supporting rib system enabling the tire to have reliable working elasticity is composited, and an anti-puncture pressure bearing working area, an assembly force bearing working area and an assembly limiting elastic working area are formed on the surface of the tire, so that the inflating-free pneumatic tire has reliable working elasticity, an excellent anti-puncture function and a longer reliable working service life; moreover, compared with a conventional automotive inflatable tire, the inflating-free pneumatic tire has general interchangeability, high practicality and excellent economical efficiency.
