Abstract: The invention concerns a tubular-tire for bicycles and its assembly on a mounting-rim of the channel type--that is normally used in combination with the usual tires having a beaded edge.The tubular-tire of the invention has a tunnel-shaped carcass profile, in the plane of the cross-section, provided with a supporting-base which is substantially concave in the center and flat at the sides and with also having two sidewalls that join together in a substantially semicircular vault.The radially inner portion of the sidewalls is joined, at the supporting base, at an angle of less than 90.degree. and it is reinforced with a pair of reinforcing elements--one textile and the other either a textile fabric, or an elastomeric liner.

Abstract: A tubular tire for cycles comprising a tubular toroidal body including an inner airtight tube to be inflated, the tire body or carcass being equipped, on the outer surface mating the wheel rim, with a rubberized tape having projecting portions such as profiles or prominences adapted to ensure a better engagement between the tire and the rim.The carcass is built by longitudinally joining together the edges of a rubberized fabric, the junction being radially external with respect to the tire and below the tread. The edges are joined either by overlapping or by abutment of the edges. In this latter case a reinforcement strip is provided between the carcass and the tread. An additional narrow strip protecting the junction is provided between the carcass and the inner or air tube.According to an embodiment the tire has a tunnel shaped cross-section obtained by suitably shaping the rubberized tape and the tire body when vulcanizing the tire.
