A pneumatic tire (10) comprising a single carcass ply (12) and at least one belt ply (24) disposed radially outward of the carcass ply (12). The carcass ply (12) comprises one or only one type of composite cord (30) consisting of one single aramid or Kevlar first yarn (34) twisted helically about one single polyester or PET second yarn (32), wherein the first yarn (34) has a modulus of elasticity greater than the modulus of elasticity the second yarn (32). Also, a composite cord (30) consisting of one single aramid or Kevlar first yarn (34) twisted helically about one single polyester or PET second yarn (32) is disclosed. The composite cord (30) has the cord construction: (1100 to 1350 dtex/1 aramid + 1350 to 1500 dtex/1 polyester)/(9 to 11)Z/(0 to 2)Z/(9 to 11)S; or (1100 to 1350 dtex/1 aramid + 1350 to 1500 dtex/1 polyester)/(9 to 11)S/(0 to 2)S/(9 to 11)Z; or (670 to 1350 dtex/1 aramid + 1100 to 1500 dtex/1 polyester)/(9 to 14)Z/(9 to 14)Z/(9 to 14)S; or (670 to 1350 dtex/1 aramid + 1100 to 1500 dtex/1 polyester)/(9 to 14)S/(9 to 14)S/(9 to 14)S; or (1200 to 1330 Denier/1 Kevlar + 1300 to 1440 Denier/1 PET)/(9 to 14)Z/(9 to 14)Z/(9 to 14)S; or (1200 to 1330 Denier/1 Kevlar + 1300 to 1440 Denier/1 PET)/(9 to 14)S/(9 to 14)S/(9 to 14)Z; or (1200 Denier/1 Kevlar + 1300 Denier/1 PET)/(13.2)Z/(13.2)Z/(13.2)S; or (1200 Denier/1 Kevlar + 1300 Denier/1 PET)/(13.2)S/(13.2)S/(13.2)Z.
