摘要： A pneumatic tire improving driving stability, road noise, riding comfort, and a fuel consumption performance in a balanced manner. The pneumatic tire includes: a bead filler made wider than a triangle formed by connecting its base and top in a cross-sectional view taken along a meridian of the tire; and a sheet-like auxiliary filler arranged from a sidewall portion to a bead portion, having thickness of 0.5 to 2.0 mm and formed of a material harder than neighboring rubber compositions excluding the bead filler. The top D of the bead filler is positioned lower than a point B1 and higher than a rim flange by at least 5 mm, a lower end C1 of the auxiliary filler is positioned higher than a point A1 and lower than a point E2, and an upper end C2 thereof is positioned lower than a point A2, apart from the point A2 by at least 10 mm, and higher than a point B2.
