Agricultural or industrial tire with polyester cord

The present invention is directed to a pneumatic agricultural or industrial tire (20) comprising a casing having at least one component reinforced with polyester cord having a polyepoxide disposed on a surface of said cord, a rubber tread (32) disposed radially outwardly of the casing, the tread having an inner tread (34) and a plurality of tread lugs (50) projecting radially from the inner tread, wherein the polyester cord is formed by first obtaining a cord through twisting together a plurality of polyester yarns, secondly treating the cord with an aqueous dispersion comprising a polyepoxide, and thirdly treating the cord with an aqueous RFL dispersion comprising a resorcinol-formaldehyde resin, a styrenebutadiene copolymer latex, a vinylpyridine-styrene-butadiene terpolymer latex, and a blocked isocyanate
