Abstract
A valve for a tubeless tire which is adapted to be secured in a bore of a tire rim comprises a tubular valve body with an outer rim surface engagement flange formed on its periphery and spaced from an inner rim surface engagement flange by the length of the bore through the tire rim. At least one of the outer or inner rim surface engagement flanges is deformed into engagement with the associated tire rim surface. Preferably, a sleeve of a soft material is located around the body between these flanges and it is deformed and compressed into a groove formed by the respective flanges over each end surface of the tire rim. The construction is such that when the valve body is inserted from the exterior of the rim to the interior, the inner flange is formed by bending over the end of an internally formed sleeve which encompasses the end of a soft body or gasket and bends it into engagement with the associated inner surface of the tire rim. When the body is inserted from the interior of the rim outwardly, the flange on the exterior surface is formed by bending over a tubular end of the deformable flange on the valve body. The deformable flange may also be formed by expanding the interior bore of the tire valve body to form an annular bead which engages over the soft body forming a gasket.
