Abstract: A tire wheel includes a pair of flanges provided on both axial ends, respectively, a pair of bead seats extending from the flanges axially inwardly, a well provided between these bead seats and concaved radially inwardly of the bead seats, and at least one hump circumferentially extending provided between the well and one of the bead seats and having a seat side inclined surface on a side of the relevant beat seat and a well side inclined surface on a side of the well to form a top as a boundary between both the inclined surfaces. The seat side inclined surface is formed by part of a conical surface intersecting at an angle of 5.degree.-35.degree. with a straight line in parallel with a tire axis. A concaved obtuse corner is formed at a boundary between the seat side inclined surface and the relevant bead seat.

Abstract: A tire wheel includes a pair of flanges provided at both axial ends, a pair of bead seats axially inwardly extending from the flanges, a well provided between the bead seats and concaved radially inwardly of the bead seats, and a hump provided between the well and at least one of the bead seats. The hump circumferentially extends and has a seat side inclined surface on the side of the relevant bead seat and a well side inclined surface on the side of the well on both sides of a crest of the hump. The seat side inclined surface of the hump includes an inclined surface continuous to the crest of the hump and an inclined surface rising from the relevant bead seat. A concaved corner having an obtuse angle is provided between the relevant bead seat and the inclined surface rising from the relevant bead seat.

Abstract: A pneumatic safety tire with a pair of annular rubber reinforcements having crescent sectional shape and applied to a tire carcass at tire sidewalls, the rubber of the reinforcements having a JIS hardness of not less than 70, a tensile stress (Mod.sub.25) after an aging test of not less than 10 kg/cm.sup.2, and a repulsive elasticity by Dunlop tripsometer of not less than 65%.
