PROBLEM TO BE SOLVED: To provide a pneumatic tire in which deformation of a tread part, in particular, deformation of a tire shoulder part during high speed travel is minimized, and standing wave phenomenon is suppressed thereby enhancing travel stability.SOLUTION: A pneumatic tire 1 in which plural belt layers 16 are so provided as to be laminated, and a reinforcement belt 100 is located on an uppermost part of the belt layers. The reinforcement belt is a dimensional (dual) reinforcement belt in which belts of different raw materials are arranged, and therefore, growth and standing wave of a shoulder part during high speed travel is suppressed, cornering performance of the tire is enhanced and travel stability is enhanced, repetition deformation and a quantity of movement of a belt part in association with size growth of the tire are increased, whereby an effect for preventing a potential problem such that detachment is promoted between the belt layers is exhibited. The dimensional reinforcement belt has a duan reinforcement belt structure which is formed by a full cover reinforcement belt of one layer and full cover reinforcement belt of another layer.SELECTED DRAWING: Figure 1

    【課題】高速走行におけるトレッド部の変形、特にタイヤショルダー部の変形を最小限にとどめ、スタンディングウェーブ現象を抑えて走行安定性を向上させる空気入りタイヤの提供。【解決手段】複数のベルト層16が積層設置され、ベルト層の最上部には補強ベルト100が設置される空気入りタイヤ1で、補強ベルトは互いに異なる素材のベルトが配列された二元化(デュアル)補強ベルトとなっており、高速走行時にタイヤトレッドのショルダー部の成長及びスタンディングウェーブを抑えてタイヤのコーナリング性能を高めて走行安定性を向上させ、タイヤの寸法成長に伴うベルト部の反復変形と運動量が増加し、ベルト層間で剥離が促される潜在的な問題を防ぐ効果を奏する空気入りタイヤ。二元化補強ベルトが、一層のフルカバー補強ベルトと他の層のフルカバー補強ベルトによって形成されている、デュアル補強ベルト構造を有する空気入りタイヤ。【選択図】図1
