<p>A pneumatic tire (1) provided with bead cores (10a), a carcass layer (20), and an inner liner (30). The carcass layer (20) has turned up sections (21) formed by turning up ends (21a) of the carcass layer (20) around the outer surfaces of the bead cores (10a). Between each turned up section (21) and the inner liner (30) is provided an annular reinforcing layer (40) comprising cords (40a) tilted by 10 degrees or less relative to a line (t) tangential to a circle centering on the rotation axis of the tire. The oxygen transmission factor (P) of the inner liner (30), the thickness (G) of the inner liner (30), and the distance (D) between the inner liner (30) and each annular reinforcing layer (40) satisfy the relationship of 4 × P/G < D.</p> |
