Designs to Enhance Tire Heat Dissipation at High Speeds

Heat dissipation structure for tires that improves durability by reducing temperatures in both the crown and bead areas. The tire has heat dissipation grooves extending from the shoulder to the sidewall, with arched or wavy bottoms. This allows air to enter the grooves and dissipate heat from the tire surface, preventing excessive temperatures in the crown and bead that can degrade durability.

A tire design with improved heat dissipation to prevent overheating and extend tire life. The tire has an outer tread with concentric grooves and protruding ribs. The grooves have cooling channels that run through the ribs. This allows air circulation around the ribs to dissipate heat generated during rolling contact. The channels connect to inner tire voids for complete heat extraction.

Integrated tire radiator structure that can be manufactured during tire production using liquid rubber. The radiator is built into the tire to dissipate internal heat and extend tire life. It involves adding high thermal conductivity materials like metals, polymers, or carbon fibers inside the tire to transfer heat from the rubber to the outside. This reduces the internal temperature and prevents premature tire failure. The radiator also improves grip, load capacity, sidewall protection, and allows monitoring of tire heat.

Heat sink for tires that dissipates heat from the shoulder area while also protecting the shoulder and sidewall from impact. The heat sink is a plate with a first surface attached to the tire shoulder and a second surface with heat dissipation features. It fits into a recess in the shoulder. The plate has a protrusion on one side that mates with a concave portion on an adjacent heat sink to connect them. This allows multiple heat sinks to be chained together in the tire shoulder.

Truck tire design with enhanced cooling to prevent overheating during prolonged highway driving. The tire has a complex multi-layer carcass construction with multiple inner layers sandwiched between outer layers. The inner layers consist of a functional filling layer, a fixed layer, and a steel sheet layer. This sandwich configuration provides additional cooling channels within the tire carcass to dissipate heat generated during driving. The outer layers include the tire surface and bottom. By embedding cooling layers between the carcass layers, the tire can dissipate heat more effectively to prevent overheating and blowouts during long highway drives.

A tire design with fins that increase heat dissipation from the tread, shoulder, and sidewall. The fins are positioned between the belt and reinforcing belt in the tire. They are formed as a conductive plate to dissipate heat generated in the tire. Heat dissipation fins extend vertically from the plate and are exposed in the grooves of the tread. This allows heat to radiate into the air through the fins.

Tire with improved heat dissipation and durability in the sidewall area. The tire has multiple stepped heat dissipation units along the sidewall circumference. This allows better heat dissipation compared to a single cooling fin. The stepped design also reinforces the sidewall in areas of concentrated stress during flexing to prevent deformation. This minimizes sidewall heat buildup and fatigue.

All-steel radial truck tire with improved heat dissipation and bead durability. The tire has a protruding bead fixing part at the junction of the tread and sidewall. This bead fixing part increases rigidity and elasticity of the top of the bead retention area. It prevents excessive deformation and torsion of the tire bead when loaded or turning sharply. This prevents bead cracks, wire bursts, and fatigue failures. The protrusion also protects the bead from external impacts. Additionally, a heat dissipation groove is provided in the bead fixing part to release heat. This prevents excessive heat buildup that can degrade tire performance and safety.

Tire crown structure with heat dissipation to reduce tire temperatures and improve tire performance by allowing heat to escape. The tire crown has heat dissipation holes in the crown body communicating with the tire surface, sidewall, or grooves. Airflow through these holes removes internal rubber heat generated during driving. This prevents excessive tire temperatures that degrade rubber properties, improving tire durability, load capacity, and high-speed performance while maintaining wear resistance.

Tire with a gradual pattern and heat dissipation features to improve tire life and safety by more effectively dissipating heat. The tire has features like longitudinal and transverse grooves, mounting cavities, heat dissipation pins, side holes, and metal patches embedded in the tread. These elements absorb and conduct heat from the tire carcass and dissipate it through the tread surface. This accelerates cooling compared to just relying on the rubber tread to dissipate heat, preventing excessive tire temperatures that can cause blowouts or reduce tire life.

Rubber tire with a sidewall design that improves heat dissipation while reducing weight to reduce rolling resistance and improve fuel economy. The sidewall has concave structures formed by recessing the surface instead of adding bumps. These concave-convex pairs guide airflow over the tire, accelerating it and increasing heat dissipation. This improves sidewall cooling compared to adding bumps. The recessed concave structures reduce weight compared to raised bumps.

Tire crown structure that improves wear resistance and reduces heat generation compared to traditional tire designs. The structure includes a tire crown with heat dissipation holes in the tire body above the belt layer. These holes communicate with the tire surface, sidewall, or grooves. They allow air flow through the crown to dissipate heat. This reduces crown temperature and prevents excessive heat buildup in thick wear-resistant rubber. This improves tire durability, wear life, and performance while avoiding excessive heat degradation.

Pneumatic tire with protrusions on the sidewall to improve cooling and durability by promoting heat dissipation through airflow. The protrusions have a smaller thickness than width, and spacing between them is less than 3 times the thickness and up to 10 times. This design allows airflow to collide with adjacent protrusions in the laminar boundary layer, enhancing cooling compared to wider spacing. The narrow spacing ensures sufficient airflow into the protrusions while avoiding gaps between them.

Heat-dissipating tire design to improve tire life and prevent delamination in the shoulder region. The tire has a high crown curvature, narrower crown width, and reverse arc shoulder shape with holes and punctured grooves. These features reduce shoulder thickness, shear stress, and heat generation. The buffer layer is positioned between the upper and lower edges of the anti-friction line to avoid stress concentration.

Pneumatic tire with protrusions on the sidewall that promote heat dissipation through air cooling. The protrusions have a smaller width in the tire circumferential direction compared to their thickness. This shape creates a laminar boundary layer of air flow around the protrusions with a large velocity gradient. This enhances heat transfer from the tire to the surrounding air, improving durability by preventing excessive temperatures that degrade tire materials.

Tire design with improved heat dissipation to prevent internal heating and premature wear. The tire has grooves that extend from the sidewall into the tread. The groove shape gradually narrows from the opening to the bottom, which is a circular arc. This design allows heat to dissipate from the tread into the grooves and out through the sidewall, preventing internal heating that can cause premature wear and failure.

A tire design with improved heat dissipation to prevent internal heat buildup and core burn. The tire has grooves that extend from the sidewall into the tread. This allows heat generated in the tread during high-speed driving to dissipate into the grooves and out through the sidewall, preventing excessive heat accumulation in the tire. The grooves connect the tread and sidewall to provide a continuous path for heat transfer.

Pneumatic tire with projections on the sidewall to improve heat dissipation through air cooling. The projections have a specific shape and angle to create a favorable air flow pattern. The projections have a top surface with a tip angle of 100 degrees or less. This allows a laminar flow of air over the top surface to enhance heat radiation. The front side surface is angled slightly downward to direct air flow along the projection and prevent turbulent flow. This helps further enhance heat radiation.

Tire with heat dissipation features on the shoulder regions to reduce tire temperature during operation. The tire has heat exchange features on the outer surfaces of the shoulder regions that modify airflow over the tires to help dissipate heat. The features are designed to move air during rotation to enhance heat transfer from the tires to the environment. This helps prevent excessive tire temperature buildup during use.

Cooling structures for tires that effectively dissipate heat generated during vehicle operation, particularly at high speeds and loads. The structures have cooling fins on the tire sidewalls that are optimized for airflow and height to overcome boundary layer effects. The fins have a height equal to or greater than the airflow boundary layer thickness at the location of the fin. This ensures maximum airflow over the fins to extract heat from the tire. The height is calculated based on tire radius, air viscosity, angular velocity, and Reynolds number. Recesses are provided adjacent to the fins to recess them axially inwards relative to the sidewall. This reduces bulkiness and maintains tire integrity while still providing sufficient cooling.
