The present invention relates to a pneumatic run-flat tire and, more specifically, relates to a pneumatic run-flat tire which can secure enough hardness in case of an accident without interfering with driving performance. According to the present invention, the pneumatic run-flat tire comprises a tread portion (100), a sidewall portion (200), and a bead portion (300). Moreover, a reinforcing portion (600) is installed between a carcass (400) of the sidewall portion (200) and an inner liner (500). The reinforcing portion (600) is divided into at least two space portions by a partition wall (630), and the space portions comprises a first liquid accommodation portion (610) of a double liquid type adhesive and a second liquid accommodation portion (620) of the double liquid type adhesive.
