Abstract
A pneumatic tire includes a tread portion, a pair of sidewall portions, a pair of bead cores, a carcass layer, a pair of first bead apex rubber components, and a belt layer disposed outward of the carcass layer. In an unloaded condition where the tire is mounted onto a standard rim and inflated with an internal pressure at 50 kPa, the carcass layer has a profile that includes an outer side portion extending from a position (A) where the carcass layer separates from the belt layer to a maximum width position (B) of the carcass layer, and the pair of outer side portion is located outside a virtual arc (C) having a single radius (R) of curvature passing through the position (A), the maximum width position (B), and an outermost ends in the tire radial direction of one of the pair of first bead apex rubber components.
