Heavy Duty Tyres TRIZ Cases

A two-layer crown and circumferential reinforcement layout improves heavy-duty tyre shock resistance, wear, and bead-zone endurance without extra mass.

Bent sipe-formed rods improve tread heat conduction during vulcanization while preserving stiffness, wear resistance, and lower rolling resistance.

A straight outer groove edge and harmonic wave inner edge reduce groove cracks, keep wear uniform, and preserve traction in commercial tires.

Curved recessed groove walls in the shoulder land spread strain at the groove bottom, reducing cracks while improving uneven wear resistance.

Specific axle mounting angles on trailer wide base tires reduce irregular tread wear and extend tire service life without losing fuel-saving benefits.

Circumferential sidewall ribs and anti-ozone wax cut tire mass while helping off-road tires deflect sharp metal attacks.

A silica-filled cap layer and controlled base-layer tan δ balance wet grip, rolling resistance, wear, chipping, and tear resistance.

Defined sidewall curvature around the ply turnup and chipper lowers bead mass, heat buildup, and rolling resistance in heavy-load tires.

A buttress recess with a sloped air-entry path and air-catching wall drives deeper airflow to cool heavy-duty tires under high load.

Segmented controllable gas springs between inner and outer rims manage load, enable run-flat operation, and cut wheel wear and downtime.

Higher-wear-resistance shoulder edge portions and an optimized tread profile help heavy-duty trailer tires resist hangnail and uneven wear.

A thicker tire shoulder and controlled groove gauge reduce belt edge strain, preserve buffing margin, and improve retread yield.

A terpene resin and vegetable granules help tire rubber improve on-ice and wet grip while limiting wear and heat buildup.

A low-modulus, high-macrodispersion skim compound protects metal carcass cords from fatigue fretting corrosion without added tire cost.

Bulged sipe bottoms and a tuned R-B-E-H ratio reduce tread cracking and tearing under severe braking without sacrificing wear life.

Blending lanthanide and nickel polybutadienes with synthetic polyisoprene improves heavy-load tire abrasion, adhesion, and processing.

Optimized sidewall protrusion width, height, and rubber modulus help heavy-duty tires resist indenter damage without tearing.

Two angled elastic metal carcass layers raise heavy-duty tire load capacity while preserving obstacle absorption and perforation resistance.

Targeted circumferential belt plies under shoulder grooves suppress tread deformation and uneven wear without adding tyre mass.

Areal shoulder recesses with parallel ribs increase tire shoulder surface area to dissipate heat and protect belt edge durability.

A cap-base tread with silica-rich rubber and controlled base-layer tan delta balances wet grip, fuel efficiency, and wear resistance.

A four-ply belt with lower outer cord count and controlled ply spacing cuts rolling resistance while preserving heavy-duty tire durability.

An auxiliary belt with tuned cord angles limits shoulder radial growth and suppresses belt-edge rubber separation in low-aspect-ratio tires.

A coupled low-molecular elastomer blend improves winter tire wet and ice grip while maintaining dry braking in a simpler single composition.

Graduated base elevations in tread channels block stone trapping in the center, move stones outward, and support stiffer, more uniform tire wear.

Radial bead notches reduce heavy-load tyre wear, simplify bead reinforcement, and maintain endurance without added stiffeners.

Local groove-wall projections in a heavy truck tire reduce stone trapping at transverse groove entries while preserving water drainage.

Adding graphene to tire sidewall rubber cuts gas permeation, improves air retention, and lowers rolling resistance without hurting processing.

Air-guiding recess slopes in the tire buttress improve airflow into cooling recesses, helping dissipate heat under heavy loads.

A buttress recess with a slope and air-catching wall guides airflow and turbulence to release heat and limit crack growth in heavy-duty tires.

A sloped buttress recess accelerates airflow along its bottom to improve cooling and suppress heat buildup in heavy-duty tires.
