Run-Flat Tires for Emergency Mobility

A tire auxiliary inner support device for run-flat tires that improves safety of heavy-duty vehicles like trucks. The device has sector-shaped support blocks connected around the tire rim to provide hoop strength when the tire loses pressure. The support blocks are made of carbon fiber skeletons with locking bolts and positioning pins to adjust spacing. The carbon fiber provides high strength and light weight compared to polymer-based supports. The device allows heavy-duty vehicles to keep moving after a tire blowout without risk of failure or loss of control.

Reinforcement profile for run-flat tires that improves their zero-pressure driving capability. The profile includes a bead filler with a steel wire, a carcass frame, carcass reinforcement, an airtight part, a buffer strip, and a sidewall reinforcing component. The airtight part contacts the carcass frame and seals against air leakage when the tire loses pressure. The buffer strip between the airtight part and carcass frame absorbs deformation forces to prevent tearing. The sidewall reinforcing component provides additional strength to the sidewall. This profile design allows the tire to continue driving without air pressure for a longer distance compared to conventional run-flat tires.

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.

Run-flat tire design that improves durability and performance when driven with zero air pressure. The tire has a reinforcing rubber layer on the sidewall, a bead reinforcing layer between the carcass and apex, and a crescent-shaped reinforcing rubber layer on the shoulder. The reinforcing rubber layer on the sidewall provides rigidity. The bead reinforcing layer made of steel wire strengthens the sidewall and bead area. The crescent-shaped shoulder reinforcement reduces deformation when driven flat. These reinforcing layers improve durability and support when air pressure is low.

Vehicle tire with improved safety and durability after punctures. The tire has an internal support system that prevents excessive deformation and blowouts when air pressure is low. The support system is a cavity filled with items like airbags, balls, and fluid. These components absorb energy from impacts and expand to replace damaged ones. This allows the tire to maintain shape and support when punctured, reducing deformations and enabling safe driving until repairs can be made.

Run-flat tire with improved support and stability after blowouts. The tire has a strong explosion-proof capability to prevent vehicle instability and loss of control when a tire blows out. It achieves this by adding a support assembly with springs, frames, and sliding blocks inside the wheel hub. The assembly provides an internal buffer and reinforcement to prevent wheel hub deformation and sidewall deviation when the tire loses air pressure. This maintains vehicle balance and stability after a blowout.

Low rolling resistance run-flat tire structure that improves safety and durability when the tire loses air pressure. The tire has steel belts extending into the shoulder and sidewall areas to provide support in those locations when the tire is deflated. This prevents excessive wear and sidewall collapse. The belts also help support the tire if it loses air, allowing the vehicle to continue driving. The sidewall has reinforcement to further enhance run-flat capability. The tire has a crescent-shaped carcass in the sidewall that extends into the shoulder.

Explosion-proof tire with improved durability and comfort when run flat. The tire has an inner liner, a support rubber, and a carcass. The support rubber provides run-flat capability when the tire loses air pressure. The support rubber composition is a composite of different rubber types with varying hardnesses. This composite rubber prevents delamination and blowouts by distributing deformation forces more uniformly compared to a single rubber type. The support rubber also uses a thinner glue layer compared to a solid support, reducing tire weight and rolling resistance.

Support type run-flat tire with improved support and durability in low air pressure or flat conditions. The tire has a crescent-shaped support rubber between the inner liner and ply at the sidewalls and shoulders. This provides additional reinforcement to prevent excessive deformation when air pressure is low. The crescent shape optimizes mechanical properties and strength. The tire also has a reinforcing layer, bead ring, and apex rubber to further support the sidewalls, shoulder, and overall shape. This improves load carrying capacity and prevents rolling issues in flat tire scenarios.

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.

Run-flat tire support structure that allows a tire to continue rolling and driving for at least 60 km at 60 km/h even when completely deflated. The structure uses a thin layer of fiber cord reinforcement instead of a thick rubber support layer. This reduces weight, cost, and rolling resistance compared to traditional run-flat tires with thick rubber supports. The fiber cord layer provides sidewall flexural durability without excessive thickness and hardness. The thinner support also avoids stress concentration on the sidewall and reduces hidden safety risks.

A support structure for run-flat tires that provides improved durability and prevents delamination of tire components when running on low air pressure. The structure uses a composite support assembly at the lower sidewall section of the tire. It includes an apex, carcass cords, triangular rubber, and support rubber. The apex, bead ring, and carcass cords cover the lower sidewall. The triangular rubber connects between the carcass cords. The support rubber is inside the carcass. The triangular rubber shape prevents deformation separation between the carcass and apex. The apex elastic modulus matches the carcass. The triangular rubber thickness is maximized at the rim. This coordinated deformation prevents sub-port delamination in run-flat tires.

Run-flat tire design that allows driving on deflated tires without damage or loss of control. The tire has a crescent-shaped support rubber layer between the inner liner and ply at the sidewall and shoulder. This provides extra support when air pressure is low or zero due to leakage or blowouts. The crescent shape optimizes mechanical properties for strength and deflection. The support rubber layer prevents excessive deformation and allows normal driving.

A run-flat tire design that allows a vehicle to continue driving after a puncture without the need for a spare tire. The run-flat tire has a composite construction with a tire casing, a solid rubber tire inside the casing, and a rim. The solid tire provides support and allows the vehicle to continue driving when the regular tire is punctured or deflated. The casing prevents the rim from damaging the road when the tire is flat. The rim width is slightly larger than the casing width to prevent the rim from protruding when the tire is flat.

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.
