To suppress the breakage of a projecting portion while highly ensuring rim fixing force.SOLUTION: A solid tire 1 is for being installed to a side ring-less type rim 4. A base rubber layer 9 of the solid tire 1 is equipped with a projecting portion 11 that projects out from a tire bottom surface 2S and is fitted with a recessed portion 7 of the rim 4, on one side in a tire axial direction. The projecting portion 11 includes an outside rubber portion 12 on an outer surface 11S side, and an inside rubber portion 13 inside thereof. The outside rubber portion 12 and the inside rubber portion 13 have different rubber physical properties.SELECTED DRAWING: Figure 2
【課題】 リム固定力を高く確保しながら、突起部の破損を抑制する。【解決手段】 サイドリングレスタイプのリム4に装着するためのソリッドタイヤ1である。ソリッドタイヤ1のベースゴム層9は、タイヤ軸方向の一方側に、タイヤ底面2Sから突出しかつリム4の窪み部7に嵌合される突起部11を具える。突起部11は、外表面11S側の外側ゴム部12と、その内側の内側ゴム部13とを含む。外側ゴム部12と内側ゴム部13とはゴム物性が異なる。【選択図】図2
