To provide a two-wheeled vehicle tire which is excellent in low fuel consumption performance and grip performance.SOLUTION: A two-wheeled vehicle tire comprises a pair of bead parts and a pair of side wall parts, and a tread part which is continuous with both side wall parts and comprises one or more rubber layers including at least a rubber layer constituting an outermost surface, and has a tire outer diameter Dt (mm) of 580 mm or more. In the two-wheeled vehicle tire, the Dt and a tanδ value 70°Ctanδ at 70°C and a tanδ value 40°Ctanδ at 40°C of a rubber composition forming the rubber layer constituting the outermost surface of the tread part satisfy the following formula (1) : (Dt/450)-0.50≤70°Ctanδ/40°Ctanδ.SELECTED DRAWING: Figure 1

    【課題】低燃費性能とグリップ性能の総合性能に優れた二輪車用タイヤを提供すること。【解決手段】一対のビード部および一対のサイドウォール部と、両サイドウォール部に連なり、最表面を構成するゴム層を少なくとも含む1以上のゴム層からなるトレッド部とを備え、タイヤ外径Dt(mm)が580mm以上である二輪車用タイヤであって、前記Dtと、前記トレッド部の最表面を構成するゴム層を形成するゴム組成物の70℃におけるtanδの値70℃tanδおよび40℃におけるtanδの値40℃tanδとが、次式を満たす二輪車用タイヤ。(Dt/450)-0.50≦70℃tanδ/40℃tanδ (1)【選択図】図1
