Tyre Tread Bands/Patterns TRIZ Cases

Asymmetrical tire ribs manipulate light reflection through distinct flank slope angles to generate visual contrast effects without complex mold production.

A pneumatic tire resonator uses asymmetric narrowed necks to reduce air column resonance noise across a wide frequency range.

A pneumatic tire sipe uses distinct 3D center and side portions to manage tread deformation.

Frame-like transverse grooves in a pneumatic tyre profile rib reduce rolling noise while maintaining structural stability for improved handling.

Dual base elevations in transverse grooves support shoulder blocks to restrict circumferential movement and enhance braking stability.

A tyre tread block uses a curvilinear connection surface to form an acute corner between the lateral wall and tread.

Outboard shoulder blocks with increased axial width and specific sipe angles reduce sudden side skid during critical cornering maneuvers.

Segmented width direction grooves with specific width ratios reduce air column resonance sound while maintaining tread land portion rigidity.

A variable-width sipe tapers from the ground-engaging side to the tread interior to ensure uniform pressure engagement across opposing sipe sides.

Asymmetric sipe geometry with inclined end walls reduces deformation under curved driving loads to improve high-speed handling stability.

A tire main groove features an intra-groove with inclined portions that form a spiral water flow to enhance drainage.

Zigzag main grooves with inclined segments generate shearing force on snow, improving traction and handling performance on snowy roads.

Bridge-integrated lamellae mitigate irregular heel-toe wear and chunking while boosting traction by 30%.

V-shaped edges and subsidiary portions in tread block recesses increase snow column volume and shearing force on packed-snow roads.

An undercut sipe profile manages elastic opening and closing to lower friction, extending kilometric yield while maintaining snow traction.

A tyre tread band uses multiple wearing layers to reveal new drainage channels after initial wear.

Segmented tread blocks with opposing projected portions prevent snow clogging in main grooves, maintaining void volume and enhancing wet traction performance.

Inner incisions feature larger wave amplitudes than outer cuts to restrict block tilting and minimize sawtooth abrasion on winter roads.

Matching rubber stress values between the tread and carbon center beam prevents tearing during demolding while maintaining electrostatic charge dissipation.

A flexible gate apparatus in tire grooves deflects under water pressure while resisting air flow to reduce pattern noise.

Segmented tread profile design maintains winter grip through fine incisions while resolving durability trade-offs caused by notch forces at groove bases.

Central holes in segmented tread sipes accumulate snow to enhance grip while maintaining low rolling resistance.
