ABSTRACT:
This invention relates to a novel rubber composition having improved green properties such as high green tensile strength and high green modulus and improved hysteresis loss and cut growth property, which comprises 100 parts by weight of a diene rubber, about 20 to about 00 parts by weight of a reinforcing filler, about 0.1 to about 3.0 parts by weight of a nitroso compound having the formula (I) ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, are selected from the group consisting of a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, a hydroxyalkyl group having from 1 to 6 carbon atoms, a cycloalkyl group and an aryl group and about 0.1 to about 3.0 parts by weight of an halogenated organic compound having the formula (II) ##STR2## wherein R.sub.3 is selected from the group consisting of a hydrogen atom, a methyl group, a chlorine atom and a bromine atom and X is a chlorine atom or a bromine atom.
