Textile cables (10) used for reinforcing tires comprise a plurality of yarns (11, 12, 13) which each consist of a plurality of aramid filaments (14) and each yarn has a twist imparted thereto. The yarns (11, 12, 13) are twisted together with one another to form cables (10). The twist ratio and the twist multiplier of the cable are dependent upon the intended end use of the cable. If the cable (10) is to be used in a high flex application, such as a reinforcing element in a carcass ply of a tire, the twist ratio is in the range of 1.0 to 1.9, and the twist multiplier is in the range of 8 to 12. If the cable (10) is to be used as a reinforcing element in the tread reinforcing structure of a tire, where there is some flexing but strength is very important, the twist ratio is in the range of 1.0 to 3.0, and the twist multiplier is in the range of 5 to 7. A preferred spacing between the cables is also disclosed. |
