Abstract
A rubber composition for use in tire having good reinforcing properties and fatigue properties and an improved heat build-up is disclosed, which comprises 30 to 60 parts by weight, based on 100 parts by weight of rubber, of a carbon black having a nitrogen adsorption value (N.sub.2 SA) of 35 to 105 m.sup.2 /g, a DBP absorption value of 140 to 200 ml/100 g, a 24M4DBP absorption value of 60 to 120 ml/100 g and a .DELTA.DBP of 50 to 110 ml/100 g defined by .DELTA.DBP=DBP absorption value-24M4DBP absorption value.
