PROBLEM TO BE SOLVED: To provide a pneumatic tire having a base tread excellent in steering stability, rolling resistance characteristics and durability in a well-balanced manner and excellent in durability of the tire by using a modified cellulose fiber-containing rubber composition achieving excellent rigidity and fracture characteristics as well as a low energy loss by improving dispersibility of cellulose fibers in rubber.SOLUTION: The pneumatic tire has a base tread manufactured by using a modified cellulose fiber-containing rubber composition which comprises modified cellulose fibers (A) prepared by adding a cyclic polybasic acid anhydride (a) having a hydrophobic group and 15 or more carbon atoms to cellulose fibers to esterify, a polymer (B) for dispersion having a softening point of 135°C or lower, and a rubber component (C).SELECTED DRAWING: None

    【課題】 ゴム中でのセルロース繊維の分散性を改善することで、優れた剛性及び破断特性と低いエネルギーロスとが両立された変性セルロース繊維含有ゴム組成物を用いて、操縦安定性、転がり抵抗特性及び耐久性にバランス良く優れ、更にはタイヤの耐久性にも優れるベーストレッドを有する空気入りタイヤを提供する。【解決手段】 セルロース繊維に疎水性基を有する炭素数が15以上の環状多塩基酸無水物(a)を付加してエステル化した変性セルロース繊維(A)、軟化点が135℃以下である分散用高分子(B)、及びゴム成分(C)を含有する変性セルロース繊維含有ゴム組成物を用いて作製したベーストレッドを有する空気入りタイヤ。【選択図】なし
