A safety valve (10c) which replaces a tyre valve. An embodiment provides a generally elongate hollow main body (112) having an upper portion (116), a lower flex hose connector (114), a side tubular branch (160) having a valve seat (170) with a ball valve (172), an electronics housing (180) having a battery (182), motor (184) and a drive pin (186) for the ball valve (172). The lower flex hose connector (114) is adapted for connection to a flex hose or valve stem of the vehicle tyre. The side branch (160) branches from the main body (112) and communicates with the hollow interior (113) of the main body (112). The side branch 160 has a plurality of air exit apertures (164) at its periphery. The valve seat (170) comprises a base (192) with an aperture (196) therein through which the drive pin (186) can extend through to engage the ball valve (172). The ball valve 172 sits in the base (192) and is biased in the valve seat (170) via a spring (171) to cover the aperture (196). In use, the drive pin (186) can extend through the base aperture (196) to engage the ball valve (172), to move the ball valve (172) away from the valve seat aperture (196), and allow air to escape via the air exit apertures (164).
