Tyre Tread Bands/Patterns TRIZ Cases

Circumferential fins guide air into lug grooves to cool the tread, suppress tire temperature rise, and reduce separation risk.

A segmented sipe with axial and circumferential elements preserves edge effect as tread wears, improving cornering on ice, snow, and wet roads.

A narrowed shoulder-side groove section improves water drainage while limiting tread deformation, vibration, and uneven wear.

Tie bars placed near sipe intersections limit closed-sipe deformation, reducing heel-and-toe wear while preserving on-ice traction.

Segmented tread zones and low-void annular portions improve wet drainage, handling, and track-speed rigidity in a road-track tyre.

Closely spaced tread hole groups absorb meltwater and retain snow, improving winter tire braking on icy and snowy roads.

Opposed groove-base elevations link the shoulder fin and block row to stiffen the tread while preserving water drainage and rolling resistance.

Shallow recessed sipe connections preserve tire edge effect while limiting land-part rigidity loss, heat generation, and uneven wear.

Shifting outer lateral grooves and a higher-loss second rubber layer help preserve drainage and wet grip as tread wear reduces groove volume.

A localized sipe mix cuts mold-to-rubber bonding near sector boundaries while preserving wet and snow braking without changing tire appearance.

Tie bars in shoulder lateral grooves let tire shoulder blocks deform for ride comfort while preserving circumferential rigidity and wear resistance.

Offset inclined lug grooves in shoulder and middle land portions preserve snow shear force while evening tread rigidity to resist uneven wear.

A resin-reinforced aircraft tire tread improves chevron cut and tear resistance across landing temperatures while extending scorch time.

Raised-bottom lug grooves and offset sipe turning points preserve block rigidity while improving snow braking, control, and uneven wear resistance.

Higher outer and lower inner sipe oscillation frequencies improve tread block stability while easing tire tread extraction from the mold.

Selective inner-side lug grooves and sipes preserve tread rigidity for dry steering while improving snow traction when chains are mounted.

A tread recess keeps the spike body securely seated while lowering road-surface load and preventing spike warping on bare roads.

Inclined overlapping closed sipes increase ice friction and tread rigidity, balancing braking, driving, and turning performance.

Segmented tread grooves and partial lateral channels improve water drainage while preserving land rigidity and dry steering stability.

Segmented shoulder blocks with lateral grooves, tie bars, and circumferential sipes balance overturning resistance and shoulder wear.

Paired sipes terminating within land portions keep sipe density high for on-ice grip while preserving rigidity and controlling tread deformation.

Compressive tread contact elements with controlled void ratio and aspect ratio cut tire noise while preserving handling through deformation absorption.

Varying incision depth with an internal cavity improves tyre water drainage and wet grip while preserving tread rib stiffness.

Asymmetric inclined groove walls raise traction and braking force while preserving water evacuation to prevent hydroplaning loss.

Triangular recesses across tread blocks compact and shear snow, sustaining on-snow traction even as the tire wears.

A single-tail bottom flange stabilizes the tire stud in the tread recess, reducing shifting, wear, and traction loss on ice.
