To improve the tire transversal rigidity and further the tire contact area with the ground, that is, to improve the tire cornering power or vehicle turning performance, the tire inner sidewall portion is reinforced by a carcass turned-up end portion, a hard rubber filler, and at least one inclined cord layer by extending all the radially outward ends thereof to roughly the middle of the tire sidewall. Further, the maximum carcass width position is located radially outward away from a bead heel by a distance (V) of at least 60% of a tire section height (J) before inflation but located radially outward away from the bead heel by a distance (U) of about 55 to 75% of the above before-inflation distance (V) after inflation, and the axial bead heel distance (A) between the two opposite beads before inflation is determined smaller than that (B) therebetween after inflation. |
