Hankook Tire & Technology-Tires-Smart-Smart City-AU04-Best choice for urban transport

Pattern design

Optimized pattern for urban service.

Shoulder rib

Optimised shoulder rib width, removed tread shoulder lug and sipe.
→ Improved handling and driving stability performance.
→ Prevents shoulder edge chip-cut & irregular wear.

  • Conventional
  • AU04

3-Dimensional Sipe

Inner block, three dimensional wave in X, Y, and Z directions.
→ Improves traction, handling and mileage performance by increased block stiffness.

  • Conventional
  • AU04

Multi-zigzag groove

Amended zigzag grooves together with an optimal block arrangement provide an improved traction performance.

  • Tire structure

    Belt structure: Minimized motion of belt for low heat generation. Carcass structure: Minimized tire deformation with optimized foot shape offers control on uneven surfaces. Improved bead: Minimum bead mobility for maximum retreadability.

  • New bead compound

    New compound for improved retreadability. Greatly improved creep performance and heat aging resistance. → Decreased bead crack. Adoption of new bead compound offers extreme thermal deformation resistance → Improved retreadability and tire lifecycle.

  • Innovative Mixing System (IMS)

    Innovative Mixing System (IMS) minimizes the breakdown and oxidation of polymer chains and has a higher dispersion degree of carbon black. The effects of IMS help to strengthen the bonding force between the carbon black and rubber to ensure longer mileage and to lower the heat generation of compounds for improved fuel efficiency.

  • Stiffness Control Contour Theory Technology
    (SCCT Technology)

    SCCT Technology is designed to reduce profile deformation. If the carcass profile is not kept constant, the internal force on the carcass will be concentrated on a specific point, belt edge or carcass turn up edge. In contrast, SCCT Technology controls the dispersion of internal force for better durability.

  • Full sidewall protector

    Sidewall damage indicator (Hole-type damage indicator)

    New shape and position of the sidewall wear indicator helps to detect damage more clearly.
