Provided are an abrasion resistance improver for inorganic filler-containing rubber composition capable of giving high abrasion resistance to a rubber composition containing an inorganic filler, a rubber composition containing the abrasion resistance improver for rubber composition, a tire using the rubber composition, and a method for producing the abrasion resistance improver for rubber composition. The present invention are concerned with [1] an abrasion resistance improver for inorganic filler-containing rubber composition, including, as an active ingredient, lignin having an aldehyde yield rate by alkaline nitrobenzene oxidation of 12% by mass or more; [2] a rubber composition containing the abrasion resistance improver as set forth above in [1], a rubber, and an inorganic filler; [3] a tire using the rubber composition as set forth above in [2]; [4] a method for producing an abrasion resistance improver for inorganic filler-containing rubber composition, including, as an active ingredient, lignin having an aldehyde yield rate by alkaline nitrobenzene oxidation of 12% by mass or more, the method including steps (A-1) to (A-3); and [5] a method for producing an abrasion resistance improver for inorganic filler-containing rubber composition, including, as an active ingredient, lignin having an aldehyde yield rate by alkaline nitrobenzene oxidation of 12% by mass or more, the method including steps (B-1) and (B-2).
