HATT 3+1

Helical Advanced Technology for Truck represents a breakthrough in belt-package engineering. The 3+1 configuration adds a helically wound nylon cap layer to the conventional 3-belt structure. A wider #1 belt ensures the casing contour aligns with the tire's outer profile, improving structural integrity. A cushion between belts #2 and #3 reduces stiffness, optimizing shoulder contact area and pressure distribution.

  • Less irregular wear thanks to optimized footprint pressure
  • Dramatically extended tire life and better retreadability
  • Improved handling, safety and ride comfort
  • Weldless steel cord (3x7x0.22 HE / 3x7x0.20 HE) eliminates weak points
  • Superior belt uniformity vs. prior construction methods

Finite Element Method

See What Others Cannot. Before a Single Tire Is Built.

Every Hanksugi tire undergoes digital stress testing, thermal mapping and structural validation before it reaches the production line.

Hanksugi FEM footprint stress analysis showing contact pressure distribution

Contact Pressure Analysis

Designed Under Pressure. Proven in Motion.

This digital stress map shows how force is distributed across every zone of the tread. Hotter areas indicate greater stress concentration. Cooler areas reveal lower load intensity.

By analysing this footprint at the microscopic level, engineers adjust rib stiffness, shoulder support and contact balance before production. The result is smarter load distribution and a tire engineered for stability and extended wear.

Thermal Simulation

Heat, Mapped with Precision.

Thermal simulation shows how temperature builds across the tire's cross-section under load. Hotter zones near the crown and bead reveal where heat concentration is greatest during flex and compression.

Engineers refine material placement, structural geometry and cooling behaviour at the design stage. Better thermal balance, reduced heat in criticall zones and a casing built for sustained-speed durability.

Hanksugi FEM dynamic deformation analysis under load

Structural Dynamics

Engineered to Dissipate Stress Before It Becomes Heat.

The outer cross-section shows stress travelling through the casing under load. The inner 3D ring visualises behaviour in motion — where forces concentrate, twist and redistribute with every rotation.

Engineers refine sidewall geometry, tread support and material distribution to reduce internal stress. A structure optimized for durability, stability and thermal control at highway speed.

Full-Body Analysis

A Full-Structure View of Tire Stress.

This 3D simulation maps force across the entire tire body. Each colour band reveals how the structure reacts while the tire carries weight, flexes through rotation and handles pressure across every zone.

By modelling the complete tire, engineers optimize stiffness, balance deformation and control stress flow before physical testing begins. A tire engineered for stable handling, better load control and longer structural life.
