A radial medium truck (RMT) tire has belt or breaker plies which are reinforced by organic reinforcement cords or filaments. In one embodiment, organic monofilaments are used in the belt or breaker plies which have the following characteristics: at least 2,000 denier (2,200 dTex), a tenacity of at least 3.5 g/denier (31 cN/Tex), an initial modulus of at least 30 g/denier (265 cN/Tex) and a shrinkage of at most 6%.

A steel cord (,) for reinforcing elastomeric articles. The steel cord (,) having a plurality of strands (,). Each strand (,) having a core (,) and a sheath (,). The sheath (,) being a plurality of steel filaments that are helically wrapped about the core (,). A first strand (,) extending longitudinally through the center of the steel cord (,). The remaining strands (,) being helically wrapped about the first strand (,). The core (,) of the first strand (,) being a plurality of filaments twisted together. In a preferred embodiment, the core (,) of the first strand,being three filaments twisted together.

Tires using high tensile reinforcement with values of at least 1240 N (280 lbs) for U+T type cord and at least 2000 N (450 lbs) for bunched type cord.

Cord (36) reinforced composites 26 for tires (10) or the like having cords 36 in a diameter range of 0.30 mm to 1.6 mm with a cord break strength (CBL) of N(720.4D.sup.2 -352.6D.sup.3)CE.

High strength reinforcement

The present invention relates to a radial pneumatic tire having a contoured zone located in each of the sidewalls of the tire. The contoured zone improves the sidewalls ply durability and decreases upper sidewall circumferential ply-wire breakage, also known as zipper-break. More particularly, the radial pneumatic tire comprises (1) at least one circumferential reinforcing belt; (2) a pair of sidewalls extending from opposing edges of said reinforcing belt to corresponding tire beads and containing a single reinforcing cord ply that wraps around each bead and having two terminal ends; (3) an inner cavity; (4) a contoured zone, wherein said contoured zone is (a) located between said single reinforcing cord ply and said inner cavity, (b) is circumferentially extending about the axis of the tire, (c) located in a region of each sidewall defined by the area from said reinforcing belt to the terminal ends of said single reinforcing cord ply, and (d) wherein the distance between the single reinforcing cord ply and said inner cavity is greater in the region where the contoured zone is located in comparison to the distance between the single reinforcing cord ply and said inner cavity in the region beneath said reinforcing belt.
