Road Vehicle Tyres TRIZ Cases

Different styrene levels in layered tread rubber improve road contact and wet grip during high-speed turning without sacrificing tread rigidity.

A low-As tread pattern and modified SBR-silica compound improve wet braking while preserving snow and ice grip in winter tires.

A two-yarn PA 6.6 belt bandage cord raises tangent modulus to resist centrifugal forces, limiting tire growth and vibration at high speed.

A silica, aluminum hydroxide, and silane-filled winter tread improves wet handling while preserving dry handling, snow traction, and wear.

A silica and aluminum hydroxide tread compound uses silane coupling to improve wet handling and snow traction while preserving dry grip and wear.

Curved tread surfaces and low-angle oblique grooves reduce motorcycle tire rolling resistance without sacrificing handling or wear.

Cross-free anchoring of tyre stiffening elements into inner and outer reinforcements prevents peeling stress and improves endurance and rigidity.

Shape memory alloy bands, polymer encapsulation, and fiber reinforcement create an airless tire that carries load without flats and resists diameter growth.

Near-circumferential groove portions placed close to the tread center edge cut rolling resistance while preserving handling and wear resistance.

Lowering silica pH while keeping high surface area improves elastomer dispersion, reinforcement, and wear resistance in tire treads.

Movable tread protrusions switch between grooves and higher contact area to improve wet traction, wear, and puncture resistance.

A hard pin and tuned base flange ratios preserve ice traction while reducing dynamic road impact and wear from studded tyres.

Optimized stud geometry and textile belt force distribution cut road wear while preserving grip and handling on icy and snowy roads.

A built-in anti-skid member pops up from tire grooves on demand, improving snow traction without separate chain installation or removal.

A tuned stud pin area-to-height ratio preserves icy-surface grip while reducing dynamic impact and road wear in studded tires.

Dense micro-projections on the tire sidewall preserve ozone-blocking wax performance while reducing diffuse reflection and crack formation.

Different tread layers and land-portion depths gradually expose higher-tanδ rubber, preventing abrupt wet braking changes as the tire wears.

Varying shoulder groove angles and pitch lengths disperses tread noise while preserving stiffness and resistance to uneven wear.

A softer joint portion than the tire inner member absorbs low-temperature impact and helps TPMS sensor mounts resist peeling at high speed.

A dual-foam insert with a U-shaped channel improves tubeless tyre fitting while preserving sealant flow, valve access, and rim protection.

Acidic pH and broad aggregate distribution help high-surface-area precipitated silica disperse in elastomers while preserving tire reinforcement and wear resistance.

Uneven bottom sidewall mass lowers torsional stiffness to cut vibration and tire noise while preserving reasonable handling.

Low-hysteresis lower-region compounds and a rigid sidewall layer cut rolling resistance while preserving transverse slip stiffness and handling.

A narrow jointless band and wider belt plies balance cornering response with straight-running stability in a motorcycle tire.

Higher-molecular-weight rosin ester improves rubber mixing processability while preserving wet grip, wear resistance, and rolling resistance.

Staggered land portions, inclined main grooves, and a notched center block improve drainage, wet braking, and snow traction.

Wheel-mounted IMU sensing captures rotation and orientation data to detect alignment, tread wear, and traction issues during driving.

Controlled band-cord elongation preserves tread contact shape, reducing road noise and uneven wear while supporting high-speed durability.
