Abstract: 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%.

When an organic polymer reinforcement is used in the top belt or breaker in the belt package of a tire, scrapping of tires during a retreading operation because of corrosion is greatly reduced. In addition, acceptance for retreadability is increased because of reduced top belt or breaker damage, allowing for easier preparation for the retreading.

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

Abstract: The invention is directed to several embodiments of metallic cord for the reinforcement of tires wherein one or more coaxial layers of metallic filaments are arranged around the metallic core filaments and twisted in the same direction at the same pitch. In one embodiment, the ratio of the diameter of the core filaments to the layer filaments is at least 1.28. In another embodiment, two of the core filaments have a first diameter and the third core filament has a second diameter smaller than the first diameter daimeter. In still another embodiment, two of the core filaments have a first diameter and a third of the core filaments has a second diameter smaller than the first diameter while the coaxial layer filaments have a third diameter equal to the second diameter. In another embodiment, the core has three core filaments twisted about each other and a coaxial layer of eight layer filaments arranged around the core filaments.

Abstract: Tires of a large size for use off-the-road with super tensile reinforcement having values of at least 4655N (1046 lbs) break strength for bunched type cord.

Abstract: A multi-layer circumferentially reinforced radial pneumatic light truck tire having a belt structure of at least two layers of 2+2x.35ST cord for Load Range E.

Abstract: A multi-layer circumferentially reinforced radial pneumatic light truck tire having a belt structure of at least two layers of 2.degree.2x.30HT cord for both Load Range C and D.

Abstract: A metal cord for reinforcing elastomeric articles, such as earth mover tires, comprises a plurality of metal wire-filament strands, including a center strand and multiple peripheral strands concentrically surrounding the center strand. Each of the center and peripheral strands includes multiple individual wire filaments of similar diameter having identical strand lay direction and length. Each strand has a hexagonally close-packed longitudinally uniform polygonal outline in which filaments are in concentric layers, with each individual filament being tangential to all adjacently surrounding filaments. The peripheral strands are tangential to the center strand and have a predetermined cord lay length and direction either the same as (Lang's Lay) or opposite to that of the center strand.

Abstract: 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.
