PNEUMATIC TIRE

A pneumatic tire reducing road noise without deteriorating durability and rolling resistance. In this pneumatic tire, the bead filler includes a triangle portion abutting a bead core and having a substantially triangular cross-sectional shape, and a uniform-thickness portion extending from a top of the triangle portion in a radially outward direction of the tire and having a substantially uniform thickness. An upper-end position of the uniform-thickness portion is outward, in a radial direction of the tire, from a position 1.6 times as high as the height of the triangle portion, and is at least 5 mm apart from the belt layers. A thickness of the uniform-thickness portion is thicker than 0.1 mm and thinner than 0.5 times a lower-end width of the triangle portion. The bead filler includes a plurality of rubber layers formed of mutually different rubber compositions. The rubber compositions forming these rubber layers have loss tangents (tan´) gradually decreasing from the outermost-periphery rubber layer toward the innermost-periphery rubber layer, are harder than other rubber compositions neighboring the bead filler, and have breaking elongations whose mutual differences are 50% points or less.
