A cap ply cord for tire reinforcement, the cap ply cord comprising two plies or three plies, wherein each individual ply consists essentially of a polyamide 6.6 yarn initially pretwisted in a first direction and the plies are finally twisted together in a second direction;
- wherein the first direction and the second direction are opposite to one another,
- wherein an elongation at break value of the cap ply cord is between 8% and 12% determined by ASTM D885, with a maximum moisture content of 0.5%;
- and
- wherein the cap ply cord has a minimum tenacity value of 9 g/dtex (10 g/denier), wherein the minimum tenacity value is based on a real linear density of the cap ply cord.
