PROBLEM TO BE SOLVED: To simplify construction and reduce expense of building tires, yet improve durability, handling, rolling resistance and other properties of pneumatic tires.SOLUTION: A pneumatic tire includes: a pair of beads each with an associated bead core and chafer; a single carcass ply folded about each bead so as to define a main body portion and a turnup portion that are associated with each bead; and a tread disposed radially outward of the single carcass ply, the tread having shoulder portions disposed at axial outer edges of the tread and a pair of sidewalls extending radially outward from each chafer to a location adjacent to each shoulder portion, each sidewall being disposed axially outward of the single carcass ply. The single carcass ply is reinforced with metallic cords, the metallic cords comprising filaments with diameters from 0.07 mm to 0.12 mm.SELECTED DRAWING: Figure 1

    【課題】タイヤ組立ての構成を簡略化して費用を削減し、しかも空気入りタイヤの耐久性、取扱い性、転がり抵抗、および他の特性を向上させる。【解決手段】各々がビードコアおよびチェーファーと組み合わされた一対のビードと、各ビードと組み合わされた主要本体部分および折返し部を画定するように各ビードの周りに折り畳まれた単一カーカスプライと、単一カーカスプライの半径方向外側に配置されたトレッドであって、トレッドの軸線方向外側縁部に配置されたショルダ部と、各チェーファーから各ショルダ部に隣接する位置まで半径方向外側に延びる一対のサイドウォールとを有し、各サイドウォールが、単一カーカスプライの軸線方向外側に配置されたトレッドとを含む。単一カーカスプライは、直径が0.07mm〜0.12mmであるフィラメントを有する金属製コードによって補強される。【選択図】図1
