What is claimed is: 1. A pneumatic tire comprising a wirecoat composition comprising (A) a sulfur-vulcanized rubber compound; and (B) the reaction product of (1) a methylene acceptor; and (2) a combination methylene donor comprising from 0.2 to 0.6 phr of hexamethylenetetramine and an amount of at least one additional methylene donor, wherein the weight ratio of said at least one additional methylene donor to said hexamethylenetetramine ranges from about 12:1 to about 3:1 wherein the at least one additional methylene donor is selected from N-substituted oxymethyl melamines of the formula: wherein X is hydrogen or an alkyl having from 1 to 8 carbon atoms, R1, R2, R3, R4 and R5 are individually selected from the group consisting of hydrogen, an alkyl having from 1 to 8 carbon atoms, the group--CH2OX and their condensation products. 2. The tire of claim 1 wherein said rubber comprises a member selected from the group consisting of medium vinyl polybutadiene, styrene-butadiene rubber, synthetic cis-1,4-polyisoprene, synthetic 3,4-polyisoprene, natural rubber, cis-polybutadiene, styrene-isoprene rubber, styrene-isoprene-butadiene rubber, acrylonitrile-butadiene rubber, carboxylated acrylonitrile-butadiene rubber and mixtures thereof. 3. The tire of claim 1 wherein said additional methylene donor comprises a member selected from the group consisting of hexakis-(methoxymethyl)melamine, N,N',N"-trimethyl/N,N',N"-trimethylolmelamine, hexamethylolmelamine, N,N',N"-dimethylolmelamine, N-methylolmelamine, N,N'-dimethylolmelamine, N,N',N"-tris(methoxymethyl)melamine, N,N'N"-tributyl-N,N',N"-trimethylol-melamine, hexamethoxymethylmelamine, and hexaethoxymethylmelamine. 4. The tire of claim 1 wherein said additional methylene donor comprises hexamethoxymethylmelamine. 5. The tire of claim 1 wherein the amount of additional methylene donor ranges from 0.5 to 4 phr. 6. The tire of claim 1, where the methylene acceptor comprises a member selected from resorcinol, resorcinolic derivatives, monohydric phenols and their derivatives, dihydric phenols and their derivatives, polyhydric phenols and their derivatives, unmodified phenol novolak resins, modified phenol novolak resin, resorcinol novolak resins and mixtures thereof. 7. The tire of claim 1, wherein the methylene acceptor comprises resorcinol. 8. The tire of claim 1, wherein the wirecoat composition further comprises from about 0.2 to 5 phr of a cobalt compound. 9. The tire of claim 8, wherein the cobalt compound is selected from the group consisting of cobalt salts of fatty acids such as stearic, palmitic, oleic, linoleic and the like; cobalt salts of aliphatic or alicyclic carboxylic acids having from 6 to 30 carbon atoms, such as cobalt neodecanoate; cobalt chloride, cobalt naphthenate; cobalt carboxylate and an organo-cobalt-boron complex. 10. The tire of claim 8, wherein the cobalt compound is cobalt naphthenate. 11. A pneumatic tire comprising a wirecoat composition, the wirecoat composition comprising (A) a natural or synthetic diene derived rubber; (B) the reaction product of (1) from 0.5 to 5 phr of a methylene acceptor; and (2) from 0.2 to 0.6 phr of hexamethylenetetramine and from 0.5 to 4 phr of hexamethoxymethylmelamine, wherein the weight ratio of hexamethoxymethylmelamine to hexamethylenetetramine ranges from about 12:1 to about 3:1; and (C) from about 0.2 to about 4 phr of a cobalt compound. 12. The pneumatic tire of claim 11, wherein the cobalt compound is selected from the group consisting of cobalt salts of fatty acids such as stearic, palmitic, oleic, linoleic and the like; cobalt salts of aliphatic or alicyclic carboxylic acids having from 6 to 30 carbon atoms, such as cobalt neodecanoate; cobalt chloride, cobalt naphthenate; cobalt carboxylate and an organo-cobalt-boron complex. 13. The pneumatic tire of claim 11, wherein the cobalt compound is cobalt naphthenate. 14. The pneumatic tire of claim 11, wherein the methylene acceptor is resorcinol.
