Tires for Heavy-Duty Applications

Puncture-resistant all-steel radial tubeless tire for mining that reduces early tire damage due to crown punctures. The tire design features transverse blocks in the tread pattern with inner steps and stone-discharging rubber nails to prevent crown punctures from sharp objects. Between the tread and steel belt, a rubber protective layer and additional layer of rubber protect the belt. A nylon curtain is added between the rubber protective layers. This multi-layer protection reduces punctures from thick steel bars and sharp stones in mining areas where tires often fail prematurely due to crown damage.

Heavy duty truck tires with improved durability and retreadability while reducing weight. The tires have specific tread designs and materials to achieve these goals. The tread has two main areas: a central area and two edge areas. The central area width is 35-70% of the total tread width. The tread has circumferential cuts that define the areas. This configuration reduces the tread's cavity ratio in the center, preventing premature wear and damage. The tread also has hidden cavities inside the outermost layer that connect to the surface through sipe cutouts. This reduces weight. The tire's crown reinforcement has a thinner inner layer using low-elasticity cords to reduce weight. However, the outer layer uses higher-elasticity cords for durability. This allows weight reduction while maintaining strength. The tread material has specific properties like low rolling resistance and good wear

Radial tire for heavy vehicles like construction equipment that simplifies the tire design to reduce weight without sacrificing performance. The top reinforcement of the tire has a composite structure with a rigid layer and a low modulus layer. The low modulus layer is wider and outermost. This configuration provides two functions: absorbing inflation stresses and preventing buckling of the carcass cables. The ratio of the rigid layer's stress to the low modulus layer's stress is 1.2. The rigid layer has high tensile strength and the low modulus layer has low elastic modulus. This allows the low modulus layer to deform more than the rigid layer to absorb inflation stresses. The triangulation layer between them prevents overlapping ends. The tire also has a lining layer with angled reinforcements to absorb inflation stresses.

A shear band structure for tires that improves durability, reduces weight, and maintains handling response compared to traditional tire structures. The shear band is inserted between the tread and other tire components. It provides reinforcement and prevents tread delamination. The shear band is made of lightweight, high-strength materials that reduce overall tire weight while maintaining durability. It also allows for thinner treads since the shear band provides additional protection. The shear band is configured with angled reinforcement cords that fold around the inner tire layers. This provides radial stiffness without adding bulk. The angled cord geometry reduces the shear force on the tread during cornering, preventing delamination. The shear band allows for thinner, lighter tires with improved durability and handling.

Radial tire for heavy construction vehicles with a crown design that improves durability and resistance to stone damage. The crown has a tread with high void volume to reduce heat buildup, but also has narrow, deep cuts called "effective cuts" that penetrate the tread and crown reinforcement. These cuts provide airflow while maintaining contact between the tread and crown. The cuts prevent stones trapped in the tread from penetrating and damaging the crown reinforcement. The cuts also have reinforced layers to resist stone impact. The crown reinforcement has a multi-strand elastic cable for permeability and a reinforced carcass. This prevents heat buildup and stone penetration in the crown for longer tire life.
