Tire with cellular rubber tread running surface

A tire with a circumferential tread with its outer running surface comprised of an integral cellular rubber wherein said rubber is a rubber composition comprised of, based upon parts by weight per 100 parts by weight rubber (phr):

• (A) at least one conjugated diene-based elastomer,
• (B) about 20 to about 150 phr of reinforcing filler for said tread rubber composition wherein said reinforcing filler is comprised of:
• (1) about 40 to about 150 phr of particulate, rubber reinforcing carbon black having a DBP (dibutyl phthalate) adsorption value (ASTM D2414) in a range of from about 90 to about 170 cc/100 g together with an Iodine adsorption value (ASTM D1510) in a range of from about 75 to about 230 m2/g, and
• (2) optionally from zero up to about 20 phr of precipitated silica, and
• (C) a resin as a reaction product of a methylene donor compound and a methylene acceptor compound;
• wherein said methylene donor compound is comprised of at least one of hexamethylene tetramine, hexamethoxymethylmelamine, hexaethoxymethylmelamine and ethoxymethylpyridinium chloride;
• and N-methylol derivatives of melamine such as, for example N,N′,N″-trimethylolmelamine, N-methylolmelamine and N′,N″-dimethhylolmelamine;
• and
• wherein said methylene acceptor compound is comprised of at least one of phenolic cashew nut oil resin, resorcinol, resorcinol monobenzoate, polyhydric phenoxy resin and reactive phenol formaldehyde resin.
