ABSTRACT OF THE DISCLOSURE A stair nosing is constituted by a flat tire frame for lying on a tread of a stair, a non-skid flat tire adapted to be snappedly engaged to the flat tire frame and a tongue-shaped protector for the engaging portion of the flat tire frame and the non skid flat tire. The non-skid flat tire comprises a connecting plate of rigid synthetic resin having the flange with rib at one edge and a non-skid flat tread of flexible synthetic resin integrally formed on the upper surface of the connecting plate. The tongue-shaped protector is integrally formed with the non-skid flat tread so as to cover the engaging portion spacedly located from a riser of the stair when the non-skid flat tire is secured to the flat tire frame.
