The invention relates to a spare tire and a jack lifting device. The spare tire comprises a rocking handle, a lifting rod, a wheel nut wrench and screws, wherein a bent part is arranged at one end of the rocking handle; a first connecting part is arranged at the other end of the rocking handle; a first positioning groove is formed in the first connecting part; a second connecting part is arranged at one end of a lifting rod body; a third connecting part is arranged at the other end of the lifting rod body; the first connecting part extends into the second connecting part; the second connecting part is of a hollow tube structure; a threaded hole is formed in the second connecting part; the third connecting part is in connection matching with the wheel nut wrench. According to the technical scheme of the invention, a rectangular cross section of the first connecting part forms a cooperation structure, so that the relative position of the rocking handle and the lifting rod is defined, and the rocking handle and the lifting rod can be locked by screws, and due to a rectangular solid structure, sufficient deformation resistance can be ensured when the spare tire rocking handle is operated.
