A pneumatic tire is disclosed comprising a carcass and a tread (10) located radially outward of the carcass and extending between the tire sidewalls. The tread (10) provides a radially outermost tread running surface (12) and comprises a first tread layer (14) comprising a first rubber compound and a second tread layer (16) comprising a second rubber compound. The second tread layer (16) is located radially adjacent to the first tread layer (14). The first rubber compound is compositionally distinct from the second rubber compound. The second tread layer (16) comprises one or more integrally formed extensions of the second tread layer (16) extending radially outwardly toward the tread running surface (12). Each of the integrally formed extensions of the second tread layer (16) comprises or forms or encloses a circumferentially continuous groove (20) and at least one reinforcement zone (24, 26) disposed on only one or on both lateral sides of the groove (20). The first rubber compound comprises 100 parts by weight of at least one diene based elastomer, and from 1 to 150 phr of silica. The second rubber compound comprises a diene base elastomer, from 50 to 120 phr of a filler, wherein at least 20 phr of the filler is a carbon black having an iodine adsorption number of at least 100 g/kg, from 1 to 45 phr of a methylene acceptor, from 1 to 25 phr of a methylene donor, and from 1 to 30 phr of at least one additive selected from the group consisting of carbamic resins, liquid diene based polymers having a number average molecular weight in a range of from 1000 to 25000, and aromatic hydrocarbon resins.
