Pneumatic tire

A light truck pneumatic radial tire comprising:

• a tread portion;
• a pair of sidewall portions;
• a pair of bead cores;
• a carcass layer comprising at least one carcass ply extending between the pair of bead cores through the tread portion and the pair of sidewall portions;
• a pair of first bead apex rubber components each disposed outward in a tire radial direction of a respective one of the pair of bead cores;
• and
• a belt layer disposed outward in the tire radial direction of the carcass layer,
• wherein
• the light truck pneumatic radial tire has a standard internal pressure of 350 to 600 kPa,
• in an unloaded condition where the tire is mounted onto a standard wheel rim and inflated with an internal pressure at 50 kPa, the carcass layer has a profile in cross-section on each axial side of the tire that comprises an outer side portion, the outer side portion extending from an axial position A where the carcass layer separates from the belt layer near an outer end of the belt layer in the tire axial direction to a maximum width position B of the carcass layer profile,
• the respective outer side portion is located outside a virtual arc C0 having a single radius R0 of curvature passing through the position A, the maximum width position B, and an axial position C of an outermost end in the tire radial direction of a respective one of the pair of first bead apex rubber components, and
• a distance H1 in the tire radial direction from a bead baseline to the respective maximum width position B is in a range from 0.40 to 0.50 times a maximum distance in the tire radial direction from the bead baseline to the profile.
