Road Vehicle Tyres TRIZ Cases

Molded recessed or projecting sidewall elements raise passenger tire load capacity while limiting cracking, noise, and comfort tradeoffs.

A thicker tread-side inner rubber with tuned loss tangent cuts exterior and interior EV tire noise without sacrificing stability or fuel efficiency.

A circumferential crown layer placed outside crossed metal plies cuts shear stress, prevents metal debris, and improves metropolitan tyre wear life.

Optimized PA 6.6 belt bandage cords raise tangent modulus to improve high-speed tire stability, curb growth, and resist vibration.

A layered tread with thicker low-loss undertread at the center and thinner shoulders cuts heat build-up while preserving crack resistance.

FFT analysis of wheel speed signals estimates tire tread depth while reducing errors from pressure, speed, and road roughness.

A cap-base tread with selective intermediate layers cuts rolling resistance while limiting wet grip loss from abrasion and improving crack resistance.

Segmented tapered jagged shoulder grooves improve water discharge while preserving tread block rigidity for stable wet and dry steering.

A two-sub-layer tire sidewall separates demolding elasticity from low-hysteresis rubber to cut rolling resistance without hurting industrial performance.

A thicker tread-side inner rubber and thinner sidewalls cut cabin noise while limiting rolling resistance and preserving high-speed durability.

Movable tread sections and an elastic linking layer let the tyre expel water, maintain traction, and resist punctures across changing road conditions.

A winter tread blends low-Tg modified SBR, silica, resin, and octyloleate to improve wet braking without sacrificing snow and ice grip.
