Tyre Tread Bands/Patterns TRIZ Cases

Angled widened shoulder sipes preserve water evacuation as tread wears while suppressing pattern noise in pneumatic tires.

Bent circumferential sipes with chamfered edges improve snow traction while preserving dry-road steering stability in tire tread blocks.

Bisector-aligned thin grooves connect block notches to improve tire traction while limiting heel-and-toe wear and block deformation.

An asymmetric tie-bar in the tyre shoulder land improves steering stability by keeping ground pressure more uniform on dry roads.

Chamfered shoulder groove walls spread ground pressure to curb heel-and-toe wear while preserving tyre braking and steering stability.

Stepped chamfered tread block corners compact and shear snow to improve tire traction and grip on snowy roads.

A 3D sipe with sinusoidal and semicircular connections boosts tread block stiffness while improving wet traction, wear resistance, and braking.

Narrow grooves and shoulder sipes crossing the tread end cut pattern noise while preserving tread stiffness, braking grip, and wear resistance.

Incision-like grooves between offset pocket grooves help a tire tread rib balance snow traction, water drainage, and low road noise.

Shorter shoulder sipe pitch and no lateral grooves reduce tread noise while maintaining wet traction and circumferential rigidity.

Asymmetric crown arcs and groove volumes balance wet handling with lower local contact pressure and uneven wear under negative camber.

A two-layer tread sub-layer uses lower- and higher-stiffness rubber compounds to cut rolling resistance while preserving cornering stiffness.

Angled buttress protectors improve tire visibility and appearance while preserving muddy-road traction, cut resistance, and low mass.

Asymmetric shoulder sipe chamfers improve braking and cornering grip while limiting noise deterioration in tire tread design.

Layered cap, intermediate, and base rubbers lower rolling resistance while preserving wet grip through tuned loss tangent distribution.

Raised portions at tread groove intersections cut air accumulation, reducing rolling noise and resistance while preserving snow traction.

Offset rubber ribs form a labyrinth seal in tyre grooves to block stone ingress to the groove base while preserving water drainage and wet braking.

Edge recesses replace extra grooves to let tread blocks bend like hinges, reducing uneven wear, water turbulence, and improving snow traction.

Chamfered leading and trailing tread block edges raise snow contact pressure while preserving stiffness for dry braking.

Step-shaped tread rib recesses improve water drainage in low-tread-depth tires while preserving rib stiffness, dry handling, and noise.

Complex bent main grooves and varied block layouts preserve unpaved-road traction while suppressing pattern noise and air column resonance.

Asymmetric chamfers in inclined tread grooves improve braking by limiting edge draw-in while preserving tire noise performance.

A widened inner sipe section helps worn tread land portions retain contact area and wet grip by limiting stiffness increase.

A stepped zigzag circumferential groove keeps tread rigidity while sustaining water drainage, traction, and wear resistance near end-of-life.

A shaped circumferential main groove uses controlled area and width ratios to block stone biting while preserving traction, drainage, and moldability.

Angled micro-incisions segment the shoulder tread rib to reduce lateral static friction and maintain tire-road contact during cornering.

A widened sipe with larger inner cross-sectional area limits stiffness growth during tread wear to preserve wet grip and road contact.

Inclined transverse sipes overlapping connecting sipe regions improve ice and snow grip while resisting tread shear and dry-road steering loss.

Shallow narrow grooves opening to main tread grooves boost snow column shear force while preserving land rigidity against uneven wear.

A dual-layer covering on tread contact elements balances edge effect and wet traction across temperatures without sacrificing wintry performance.

Inclined lug grooves and second sipes form triangular tread blocks that improve wet drainage while preserving land portion rigidity.

Curved shoulder and intermediate lug groove placement balances tread rigidity and water drainage for stable steering on dry and wet roads.

Alternating buttress grooves and ridges improve snow traction while limiting stiffness differences that can weaken dry-road steering stability.

Widening circumferential grooves toward the heel side increases snow shearing and traction while maintaining dry-road performance.

Segmented protrusion regions vary spacing and reflection angles to expand tire decorative contrast while limiting light concentration.
