A rim (1) of a tire wheel (TW) comprises a drum (1a) and inboard and outboard tire bead sheets (1b, 1c) extending radially from both sides of the drum (1a). A bead portion (3a) of a pneumatic tire (3) is press bonded to the outboard tire bead sheet (1b). A pneumatic tire pressure sensor (2) is fixed to the rim (1). When the pneumatic tire (3) is mounted on the tire wheel (TW), or when the pneumatic tire (3) is removed from the tire wheel (TW), a protector (4) which is fixed to the rim (1) protects the pneumatic tire pressure sensor (2) such that the bead portion (3a) removed from the outboard tire bead sheet (1b) does not interfere with the pneumatic tire pressure sensor (2).
