Pneumatic Tyre Reinforcements TRIZ Cases

A layered tire-reinforcing cable raises surface fracture energy to resist punctures, transverse embrittlement, and breakage under obstacle stress.

A zigzag rubber-coated belt cord layout controls rigidity differences across the tire width to reduce uneven tread wear.

Low-stress metal filaments in tire conductive threads absorb repeated deformation, reducing breakage while maintaining electrical conductivity.

Adjusting outermost carcass and belt cord angles helps offset shear strain at the tread shoulder, reducing uneven wear and improving durability.

Partially embedded metal-textile cords improve tyre adhesion to elastomeric material, cut hysteresis, and reduce reinforcement weight.

Optimized shoulder rubber ratios and reduced carcass ply wrap cut aircraft tire weight while protecting belt edges, cuts, and heat.

A conductive edge cover layer extends beyond the innermost ply to keep carcass contact, preserving tire conductivity without adding semi-finished products.

A polymer-filled metal cord creates a rigidity gradient at the rubber interface, easing stress concentration and improving durability.

Composite aramid carcass cords cut aircraft tire layer count to reduce bead fatigue, hysteresis losses, and weight under landing loads.

A fiber-reinforced plastic ring replaces multiple tire reinforcement layers to cut weight, simplify production, and tune asymmetric stiffness.

A calendered thin inner rubber layer around reinforced carcass plies improves airtightness, strength, homogeneity, and heat behavior.

A rigid elastomeric sidewall insert limits bending in corrugated crown tires, improving vehicle behavior without major weight or rolling resistance penalties.

A three-layer tire belt uses smaller second and third ply angles to cut carcass shear stress and improve power transfer efficiency.

By placing outer carcass ply ends close to the inner ply upturn, this tyre structure cuts rolling resistance and weight while keeping sidewall stiffness.

A layered multi-strand tire cord balances break strength, flexibility, and elastomer penetration to improve bending endurance and corrosion resistance.

A shoulder circumferential sipe placement suppresses tread compressive strain to cut rolling resistance while preserving wet-road grip.

Twisted polyester and nylon tire cords balance lower manufacturing cost with ride comfort and compression fatigue resistance in tire plies.

A cotton spun yarn weft with controlled fineness and density stabilizes cord-fabric slitting width and warp count for more uniform tires.

Organic fiber carcass cords, wide rim geometry, and a high-performance inner liner help small bus tires carry higher loads without harder bead folding.

Wider wire spacing in a metallic tire cord lets elastomer penetrate between wires, improving adhesion, reducing corrosion risk, and limiting cutting forces.

A 1×4 steel belt cord with controlled diameter and cord density spreads stress more evenly to reduce cord-rubber separation and extend tire life.

Twisted metallic wires create part-load elongation that lets elastomer penetrate the cord, improving adhesion, rigidity, and corrosion resistance.

A shortened second carcass ply reinforces the tread zone to resist pressure deformation while keeping tire weight and rolling resistance low.

Edge cover rubber and a 1.0-3.0 mm belt-ply gauge limit belt-end strain in low-profile tires while preserving load capacity and cabin space.

A conductive member links the bead chafer to conductive reinforcement layers so static electricity can reach the road without raising rolling resistance.

Non-overlapping tire belt bandage sections with lower-density center cords improve wear uniformity, cut rolling resistance, and support high-speed durability.

A core-insertion hooping ply helps single-working-ply tires keep crown strength and resist high-speed deformation under repeated stress.
