Реферат: There is disclosed a pneumatic tire for heavy duty use having a tread which is composed of a rubber composition comprising 100 parts by weight of an (A) isoprene-based rubber and 30 to 70 parts by weight of (B) carbon black which has a nitrogen-adsorption specific surface area (BET) of 120 to 160 m2/g a dibutyl phthalate absorption amount (DBP) of 80 to 130 ml/100 g a most frequent value of aggregate diameter distribution (Dst) of 60 to 70 nm and a half peak width (DELTAD50) of 65 to 80 nm, and as the case may be, 3 to 20 parts by weight of (C) silica which has a nitrogen-adsorption specific surface area (BET) of 210 to 260 m2/g and an oil absorption amount of 200 to 260 ml/100 g. The above pneumatic tire is capable of enhancing the low heat-buildup property without detriment to the abrasion resistance of a tread rubber, and favorably reconciling both the low heat-buildup property and the abrasion resistance of itself.
