HATT 3+1

Helical Advanced Technology for Truck represents an advance in belt package engineering. The 3+1 configuration adds a helical nylon ply wound over the traditional 3-belt steel structure. A wider Belt #1 ensures the casing contour aligns with the outer tyre profile, improving structural integrity. A shock-absorbing layer between Belts #2 and #3 reduces rigidity, optimising shoulder contact patch and pressure distribution.

  • Less uneven wear thanks to optimised footprint pressure
  • Dramatically extended tyre service life and improved retreadability
  • Better handling, safety and comfort
  • Weld-free steel cables (3x7x0.22 HE / 3x7x0.20 HE) eliminate weak points
  • Superior belt uniformity versus previous-generation construction methods

Finite Element Method

See What Others Cannot. Before a Single Tyre Is Made.

Every Hanksugi tyre undergoes digital stress testing, thermal mapping and structural validation before reaching the production line.

Contact Pressure Analysis

Designed Under Pressure. Validated in Motion.

This digital stress map shows how force is distributed across each area of the tread. Warmer areas indicate higher stress concentration. Cooler areas reveal lower load intensity.

By analysing the footprint at a microscopic level, engineers adjust rib rigidity, shoulder support and contact balance before production. The result is more intelligent load distribution and a tyre designed for stability and extended wear.

FEM thermal simulation showing heat distribution across the cross-section of a Hanksugi tyre

Thermal Simulation

Heat, Mapped with Precision.

The thermal simulation shows how temperature accumulates through the tyre cross-section under load. The warmer areas near the crown and bead reveal where heat concentration is highest during flexion and compression.

Engineers refine material placement, structural geometry and cooling behaviour at the design stage. The result is better thermal balance, reduced heat in critical areas and a casing built for durability at sustained speeds.

Structural Dynamics

Designed 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 each rotation.

Engineers refine sidewall geometry, tread support and material distribution to reduce internal tension. The result is a structure optimised for durability, stability and thermal control at speed.

Full Body Analysis

A Complete Structural View of Tyre Stress.

This 3D simulation maps force throughout the entire tyre body. Every colour band reveals how the structure responds as the tyre bears weight, flexes during rotation and manages pressure across all zones.

By modelling the complete tyre, engineers optimise rigidity, balance deformation and control stress flow before physical testing begins. The result is a tyre designed for stable handling, better load control and extended structural life.
