Tyre Tread Bands/Patterns TRIZ Cases

A pneumatic tire tread uses additional transverse grooves in specific shoulder blocks to equalize circumferential and transverse rigidity.

Varying groove curvature improves snow traction while maintaining dry road steering stability.

Partial lateral grooves in the outboard middle land portion balance snow traction against steering stability by suppressing excessive rigidity reduction.

Segmented tread blocks combine distinct rubber compounds to resolve the trade-off between wet grip reliability and energy loss from rolling resistance.

Segmented tread grooves optimize water evacuation while maintaining land portion rigidity in pneumatic tires.

Alternating extension sections in tire treads create dynamic opening angles that improve snow grip without reducing dry traction rigidity.

Assigning high tan delta rubber to side ribs and carbon-rich compounds to central ribs resolves the wet grip versus dry wear trade-off.

Shoulder sipes feature deep and shallow portions aligned with a zigzag leading edge vertex, reducing chunking risk while maintaining traction on icy roads.

Segmented narrow axial grooves with specific inclinations improve aquaplaning resistance while maintaining tread rigidity and steering stability.

A pneumatic tire tread block features a tapered tip end connected to an adjacent block via a bridge portion at constant land height.

Varying opening depths in inner and outer tread regions correct uneven weight balance while preserving traction performance.

Segmented electrically conductive rubber guides static discharge to reduce rolling resistance and heat build-up.

Varying incision depth across tyre blocks manages internal stress concentrations, preventing premature cracking while maintaining mechanical strength and grip.

Larger axial groove curvature radii increase land portion rigidity, resolving steering stability deterioration caused by reduced axial rigidity.

Segmented pneumatic tyre tread uses distinct rubber compounds to balance rolling resistance with handling stiffness.

Narrow-angle slits connect to zigzag groove bends, equalizing block rigidity and suppressing uneven shoulder wear.

Segmented tread recesses combine fine incisions with tubular channels to maintain aquaplaning resistance as wear reduces groove volume.

Shallow circumferential grooves widen into transverse sections to break up water films, restoring block-to-road contact on wet surfaces.

An intermediary safety unit with coiled lining plates prevents slippage and piercing vulnerability in vehicle tires.

Segmented flexible blades in tire tread grooves alter air resonant frequency, reducing rolling noise while easing mold demolding.

Serrated tread groove walls sweep away water films to maintain ground pressure and improve braking performance.

L-shaped groove segmentation in tire shoulder land sections creates block segments that maintain structural rigidity while enabling fluid flow.

Varying stud embedding depths prevent pin drop on hard surfaces while ensuring continuous traction on snow and ice.

Segmented spike recesses with varying depths capture ice particles while preventing channel clogging on rough surfaces.

Asymmetrical stereoscopic sipes distribute rigidity across the tread, enhancing dry steering stability while maintaining ice braking performance.

Variable depth serpentine grooves resolve the trade-off between hydroplaning resistance and tread wear life by localizing deep channels at shoulders.

Segmented tread grooves balance drainage efficiency with driving stability by extending primary channels to the edge while terminating auxiliary ones.

Curved groove walls and rounded rib transitions eliminate stress concentrations that cause irregular wear and stone trapping.

Segmented tread pattern with inclined grooves shears snow while maintaining outboard middle land rigidity to prevent steering stability loss.

Ramp-shaped base elevations stiffen shorter pitch tread blocks, resolving non-uniform wear caused by immediate succession of varying pitch lengths.

Inclined grooves and selective sipes improve traction on low friction roads while maintaining wear resistance.

Omega-shaped sipes with alternating widths maintain open channels for snow and water absorption during tread deformation.

Inclined sipe bottoms prevent fatigue crack propagation while maintaining fuel economy and tread stability.

Alternating inclined surfaces and concave portions in circumferential grooves suppress block tilting deformation and hydroplaning.

Concave flank indentations shorten drainage paths to prevent water vortices, reducing rolling noise in the 1,000 Hz range without sacrificing rib stiffness.

Oppositely inclined shoulder oblique grooves provide structural support for compacted snow, resolving insufficient lateral grip during cornering.

Pyramid-like elevations with partial depth prevent groove resonances while promoting stone ejection for uniform wear.
