PROBLEM TO BE SOLVED: To provide a pneumatic tire having a filler-less structure that is excellent in improvement effect for brake performance and reduction effect for rolling resistance.SOLUTION: A pneumatic tire includes: a pair of bead parts 1 embedded with an annular bead core 6; and a carcass 4 provided between the pair of bead parts 1. The pneumatic tire has a filler-less structure where the carcass 4 is folded back without laying a bead filler around the bead core 6. A tire thickness measured in a direction vertical to a carcass line is 1.2 times or less as thick as a width W6 of the bead core 6 on a rim line 7 and 4.2 mm or less in a tire maximum width position 8.SELECTED DRAWING: Figure 1 【課題】制動性能の向上効果と転がり抵抗の低減効果に優れたフィラーレス構造の空気入りタイヤを提供する。【解決手段】環状のビードコア６が埋設された一対のビード部１と、その一対のビード部１の間に設けられたカーカス４とを備え、ビードコア６の周りでビードフィラーを配設することなくカーカス４が折り返されたフィラーレス構造の空気入りタイヤであって、カーカスラインに垂直な方向で測定されるタイヤ厚みが、リムライン７においてビードコア６の幅Ｗ６の１．２倍以下であり、タイヤ最大幅位置８において４．２ｍｍ以下である。【選択図】図１
