To provide a pneumatic tire that can exert excellent steeling stability continuously during running at a high speed.SOLUTION: A pneumatic tire includes a ply 10 including a plurality of cords 11 and side wall rubbers 3G. In each of the cords 11, a plurality of filaments 14 having an outer diameter d are twisted. In each of the cords 11, a ratio D/d of an average diameter D of the cord to the outer diameter d of the filament 14 is 28 or more. The D/d and loss tangents tanδ of the side wall rubbers 3G satisfy the following formula (1): (tanδ)/(D/d)×1000≤5.5 (1).SELECTED DRAWING: Figure 1
【課題】高速走行時において優れた操縦安定性を持続して発揮し得る空気入りタイヤを提供する。【解決手段】複数のコード11を含むプライ10と、サイドウォールゴム3Gとを含む。コード11のそれぞれは、外径dの複数のフィラメント14が撚り合わされている。コード11のそれぞれは、コード平均径Dとフィラメント14の外径dとの比D/dが28以上である。比D/dと、サイドウォールゴム3Gの損失正接tanδとが、下記式(1)を満足する。(tanδ)/(D/d)×1000≦5.5 …(1)【選択図】図1
