PROBLEM TO BE SOLVED: To provide a pneumatic tire and a cross-linking rubber composition excellent in abrasion resistance.SOLUTION: A pneumatic tire comprises: bead cores respectively provided for a pair of right/left bead parts; a carcass ply extending from a crown part through both sidewalls to both bead parts and moored by the bead cores; and a tread made of the following cross-linking composition. A cross-linking rubber composition includes two kinds or more of rubber constituents and filler in which volume of a gap part is 7.5% or less when elongated by applied stress of 3.0 MPa, and the filler distribution property D represented by the following formula (I) is 2.0 or less. D=(A/B)/(A/B)(I) (Ais volume fraction of rubber constituent A in the filler gel; Bis volume fraction of rubber constituent B in the filler gel; Ais volume fraction of the blended rubber constituent A; Bis volume fraction of the blended rubber constituent B.)SELECTED DRAWING: Figure 2
【課題】耐摩耗性に優れた空気入りタイヤおよび架橋ゴム組成物の提供。【解決手段】左右一対のビード部に夫々設けられたビードコアと、クラウン部から両サイドウォール部を経て両ビード部に延び、前記ビードコアに保留されたカーカスプライと、下記架橋組成物からなる、トレッドと、を備える空気入りタイヤ。２種以上のゴム成分およびフィラーを含有する架橋ゴム組成物であり、３．０ＭＰａの印加応力による伸長時の空隙部の体積が７．５％以下であり、下記式（Ｉ）で示されるフィラー分配性Ｄが２．０以下である架橋ゴム組成物。Ｄ＝（Ａ1／Ｂ1）／（Ａ0／Ｂ0）（Ｉ）（Ａ1はフィラーゲル中のゴム成分Ａの体積分率；Ｂ1はフィラーゲル中のゴム成分Ｂの体積分率；Ａ0は配合したゴム成分Ａの体積分率；Ｂ0は配合したゴム成分Ｂの体積分率）【選択図】図２
