Zusammenfassung:	PURPOSE:To obtain the subject composition, having both high level of abrasion resistance and low heat build-up properties and improved in quality by blending specific carbon black in a specified amount in a rubber component. CONSTITUTION:The objective composition obtained by blending carbon black, belonging to a hard-based carbon black having 60-160m /g nitrogen adsorption specific surface area (N2SA), 90-150ml/100g DBP oil absorption and selective characteristics of >= a value of carbon gel (%), expressed by the formula and measured by a Soxhlet extracting method (in blending with natural rubber) in an amount of 30-100 pts.wt. based on 100 pts.wt. rubber component, such as natural rubber, and further, as necessary, a vulcanizing agent, plasticizer, etc., therewith.
