Abstract:
In a pneumatic tire, a height from a turned-up edge of a carcass layer is not more than 10 mm, a distance from a tire outer surface to the carcass layer is not less than 50% of the total gauge, a height of the bead filler is from 50% to 80% of a tire cross-section height, a cross-sectional area ratio VB/VR of the bead filler to a side reinforcing layer is not less than 0.4 and not more than 0.6, a hardness HsB of the bead filler is not less than 65 and not more than 80, and the hardness HsR of the side reinforcing layer is not less than 75 and not more than 85, a size relationship between the hardness HsB and the hardness HsR is HsB≦HsR, a value TB of tan δ is not more than 0.06, and a value TR of tan δ is not more than 0.05.
