Run-Flat Tire Technology for Improved Vehicle Safety

A long-lasting anti-puncture, anti-explosion tire with puncture alarm for electric vehicles that allows driving after punctures and prevents explosions. The tire has a thickened foam layer sandwiched between two metal films inside. The foam layer is filled with a thin foam layer. The metal films have connecting wires passing through. When punctured, the foam compresses and makes contact with the metal films, completing a circuit to trigger an alarm. This allows driving with punctures for longer than conventional tires. The thick foam prevents full deflation. The foam absorbs puncture objects and seals minor leaks. The metal films prevent explosions. The foam layer is thicker than normal for added protection.

Flat-run tire with self-puncture recovery capability that allows uninterrupted driving even after a tire puncture occurs. The tire maintains structural integrity, supports vehicle weight, and provides traction after a puncture to prevent sudden loss of pressure. The tire design involves a puncture recovery mechanism that captures and utilizes the remaining air in the tire after a puncture to provide temporary run-flat capability. It also includes a run-flat system that distributes the load evenly across the tire to prevent further damage and ensure adequate control.

Puncture-resistant low heat build-up tire with improved puncture protection and reduced internal heat build-up compared to conventional tires. The tire has a unique puncture prevention layer between the outer and inner tire layers. This layer includes a buffer, wire braid, puncture plate, gel repair fluid, and elastic protective layer. The buffer reduces external piercing force. The wire braid and puncture plate prevent inner tire punctures. The gel repair fluid seals around punctures to prevent air loss. The elastic protective layer surrounds the repair fluid. This layer setup provides enhanced puncture resistance and prevents inner tire damage from external objects. The gel repair fluid also seals around objects to prevent air loss. The buffer reduces piercing force. This reduces internal heat build-up compared to conventional tires where heat can't easily dissipate during contact with the road.

A pneumatic vehicle tire with emergency running properties that allows the tire to be driven safely for a certain distance if it loses air pressure. The tire has features like a profiled tread, multi-layer belt, sidewalls with reinforced profiles, and a carcass. The reinforced profiles in the sidewalls provide the emergency running ability. The tire can continue driving without air pressure for a limited distance before needing replacement.

Explosion-proof tire design for run-flat capability that allows stable operation after puncture. The tire has a detection chamber inside the tire. When the tire bursts, the chamber collapses and squeezes an air cushion. This squeezes a support block with a rubber tire and a telescopic rod. The rod extends into a spring-loaded sleeve. The sleeve limits rod movement to keep the block and tire fixed on the wheel hub, preventing unbalanced rolling.

Explosion-proof puncture-proof self-sealing tire that reduces the risk of tire punctures and provides a sealed inner volume to prevent air leakage. The tire has features like stab-resistant rubber, finger ports, and airtight layers to prevent penetration and seal punctures. The tire has a tread with pattern grooves and concave-convex finger ports on the sides. Inside the tread is a puncture-proof rubber layer, airtight layer, and double nylon plies. The bead rings are inside the tread. The stab-resistant rubber is fixed to the tread's inner wall. The nylon plies are attached to the tread ends. This prevents punctures and seals them via the finger ports. The airtight layers prevent air loss.

Self-repairing high-speed radial motorcycle tire with improved puncture resistance and self-sealing capability. The tire has a frosted layer on the outer surface of the airtight layer that is polished to form a rough texture. Above the frosted layer, a self-healing soft adhesive layer is applied. When the tire is punctured, the internal pressure squeezes the self-healing soft rubber into the puncture holes, sealing the tire and preventing air leakage. The frosted layer provides a rough surface that promotes adhesion of the self-healing rubber.

Puncture protection tire system that uses an onboard gas generation module to inflate the inner tube of the tire if the tire pressure drops significantly while the vehicle is moving at a certain speed. This prevents deflation and potential accidents caused by punctures. A tire pressure monitoring module and speed detection module trigger the gas generation when conditions are met. This prevents tire bursts when stationary or at low speed, reducing maintenance costs compared to traditional puncture protection tires.

Run flat tire design that allows driving even with a puncture or zero air pressure. The tire has a reinforced sidewall with a cross-compounded support rubber layer. The layer has two types of rubber with different hardnesses. This cross-compounding allows the two rubber types to interact and disperse stresses instead of concentrating in one area. This prevents fatigue failure and delamination of the support rubber in a flat tire state.

Single-sided double sidewall safety run-flat tire design that allows driving with punctures or leaks to prevent sudden tire failure at high speeds. The tire has double sidewalls with air retention cavities between them. When punctured, only one cavity ruptures since each cavity has a gas retention layer. This isolates air leaks and allows driving on a flat tire for short distances. A spare rubber ring around the wheel rim provides additional support. The tire also has reinforced crown and carcass layers to prevent punctures from propagating.

Puncture-proof tire structure that eliminates the issues of conventional self-sealing tires. The tire has a puncture-resistant aramid buffer layer between the carcass and tread. Inside the carcass, there's an airtight rubber layer and a self-sealing adhesive layer. The self-sealing layer has an outer covering adhesive layer. This configuration provides multiple layers of self-sealing adhesive sandwiched between the airtight rubber and outer covering adhesive. The inner self-sealing layer prevents peeling or agglomeration issues. The outer covering adhesive layer protects the self-sealing layer. The aramid buffer layer prevents punctures reaching the self-sealing layers.

An electric vehicle tire with puncture prevention and leakage protection. The tire has multiple airtight layers inside to prevent air leakage if punctured. In addition, a viscous layer is sandwiched between the inner layers on both the tire's sidewall and tread. This provides puncture prevention for the sidewall as well as the tread. The viscous layer prevents sharp objects from penetrating the tire and sealing the puncture.

A puncture-proof and leakage-preventing tire design that improves safety and reduces accidents by effectively sealing punctures and preventing air leakage. The tire has an inner airtight layer sandwiched between two outer airtight layers. When a sharp object penetrates the tire tread, the middle airtight layer deforms around it instead of puncturing, sealing the hole. An adhesive layer inside the tire wraps around the object to block further penetration and prevent air leakage. The airtight layers and adhesive provide puncture resistance and sealant function.

Run-flat tire with integrated pressure monitoring and sealing system to prevent blowouts and accidents. The tire has a pressure sensor and gas generator installed in an annular groove on the wheel rim. The pressure sensor contacts the inner tube and detects low pressure. If the tire strength is exceeded or punctured, the pressure drop triggers the gas generator to ignite solid fuel and generate gas. This inflates the inner tube to block punctures and allow driving on deflated tires.

Run flat tire design that allows driving even with a puncture. The tire has a reinforced bead area that extends into the tire interior. This bead support prevents the tire from collapsing when air leaks out. The support has a specific length and contains a reinforcing member with elasticity in the circumferential direction. The carcass wraps around the support at the inner end, extending to the sidewalls and outer bead surface. This provides a secure and flexible sidewall while still allowing the bead to protrude. The elastic support absorbs deflection forces from the rim when the tire is low on air, allowing limited driving distance.

Side-reinforced run-flat tire that allows safe running even when the tire internal pressure drops. The tire has a load detecting member on the outer surface of the sidewall that irreversibly changes under vertical load. This allows determining from the outside if the load-bearing reinforcing member inside the sidewall is peeling off or damaged. If the load detecting member shows a change, it indicates potential reinforcing member damage from excessive load, which can degrade run-flat performance.

A pneumatic tire that balances cushioning performance with puncture prevention by using a tread design with a unique reinforcement structure. The tread has a reinforced layer sandwiched between the inner and outer tread layers. This reinforced layer has a lower elastic modulus than the outer tread layer, but higher than the inner tread layer. This allows the outer tread to cushion while the reinforced layer seals punctures better. The lower elasticity of the reinforced layer reduces the force needed to close punctures compared to the outer tread. This provides better puncture sealing without compromising cushioning as much.

Pneumatic radial tire design for running on zero air pressure without rim damage or major tire damage when a puncture occurs. The tire has a crescent-shaped side reinforcement layer that is smaller than conventional run-flat tires. This reduces tire mass, improves ride comfort, and reduces rolling resistance. The side reinforcement layer area is 40-100% of the bead filler area. The tire also has a bead filler that is taller than conventional tires. This allows the carcass to straddle the beads in a toroid shape. This configuration enables running on zero air pressure without deforming the sidewalls excessively. The tire deflection rate when flat is 30-60%. This provides maneuverability and prevents excessive tire deformation.

Run-flat tire design with improved hydroplaning resistance and grip when running on deflated tires. The tire has grooves in the shoulder region that close when the tire is properly inflated. But when the tire loses air pressure and the shoulder contacts the ground, the grooves open and provide water evacuation to prevent hydroplaning. The grooves have buried members that separate when tension forces open the grooves. This allows the sidewall to flex and contact the road while still exposing the groove bottoms for water evacuation.

Self-supporting run-flat tire that allows continued driving on a flat tire without loss of pressure, while maintaining good ride comfort when properly inflated. The tire has an internal support feature that contacts the rim in a deflated state to support the load, but doesn't touch the rim when inflated. The support is located in the tread facing the tire cavity and includes a reinforcing rubber section and possibly a reinforcing ply. This allows the tire to travel a distance on a flat without puncture-induced deflation, while avoiding rim contact and ride harshness when inflated.
