Summary:PROBLEM TO BE SOLVED: To provide a pneumatic tire which ensures weatherability and improves traction performance.SOLUTION: A pneumatic tire comprises: a tread rubber 3c; a side wall rubber 6 covering the tread rubber 3c from a side surface of the tire; and a projection 8 formed in the side wall rubber 6. The rubber hardness of the tread rubber 3c is higher than the rubber hardness of the side wall rubber 6. The side wall rubber 6 has an inner rubber 6a and an outer rubber 6b, which branch inside and outside in a width direction, in the radial outside part. A tip P2 of the tread rubber 3c is sandwiched between the inner rubber 6a and the outer rubber 6b and disposed in the radial inner end than a radial outer end P3 of the projection 8. 【課題】耐候性を確保すると共に、トラクション性能を向上させた空気入りタイヤを提供する。【解決手段】トレッドゴム3cと、トレッドゴム3cをタイヤ側面から覆うサイドウォールゴム6と、サイドウォールゴム6に形成される突起8と、を有する。トレッドゴム3cのゴム硬度は、サイドウォールゴム6よりもゴム硬度が高い。サイドウォールゴム6は、幅方向内外に枝分かれする内側ゴム6a及び外側ゴム6bを径方向外側部に有する。トレッドゴム3cの先端P2は、内側ゴム6a及び外側ゴム6bに挟まれていると共に、突起8の径方向外端P3よりも径方向内端に配置されている。【選択図】図1
