Radial tire profile

Claim 1

A radial tire comprising: a pair of bead cores disposed in the beads of the tire; a radial carcass extending across the beads, both ends of which are turned up around the bead cores to form a main part and turned-up parts of the carcass; a tread disposed on the carcass; a rubber bead apex disposed between the main part and the turned-up part of the carcass, and extending taperingly radially outwardly along said carcass; a breaker, having high tensile cords, and disposed between the carcass and the tread; characterized in that: (a) the clip width (C1) of the tire after the vulcanizing molding is under 100% and over 85% of the rim width (C2) of a normal rim for the tire; (b) in a state of the tire mounted on a normal rim and inflated to a standard pressure, said carcass (6) having: the largest width point (D) between a radially inner first point (E1) and a radially outer second point (E2); an inflexion point (F) between the largest width point (D) and the radially inner first point (E1); an outwardly bulging outer part (21) between the largest width point (D) and the radially outer second point (E2); an outwardly bulging middle part (22) between the largest width point (D) and the inflexion point (F); and an inwardly bulging inner part (23) between the inflexion point (F) and the radially inner first point (E1), wherein the first point (E1) is defined as a point of intersection of the carcass (6) and a second line (X2) that is a perpendicular to a first line (X1) at a contact point (C) at which the first line (X1) inclined axially outwardly by 45° to the rim base contacts with the axially inside surface of the rim flange (11), and the second point (E2) is defined as a point of intersection of the carcass and a third line (X3) extending radially outwardly from the first point (E1); and the middle part (22) and the inner part (23) smoothly continue through the inflexion point (F); (c) a radial height (H2) of the largest width point (D) from the first point (E1) is under 50% and over 40% of a radial height (H1) of the second point (E2) from the first point (E1); (d) an axial distance (L1) between the largest width point (D) and the third line (X3) is over 28% and under 33% of the height (H1); and (e) an axial distance (L2) between the inflexion point (F) and the third line (X3) is under 70% and over 55% of the distance (L1).
