Product Features

  • 190% stud quantity(actual stud quantity depending on tire size) compared to Nordic regulation can enhance ice performance(it's 170% for its predecessor SW-8). With qualified Nordic Overrun test results, SW-9 is assured its caused damage on road surface can meet regulation requirement.
  • Optimized stud location allocated per stud lines enables each stud to rub efficiently against road surface to improve traction on icy roads and upgrade ice performance.
  • Unique resembling triangle shape stud carbide design has bigger ice friction  than normal round shape stud carbide to improve ice performance.
  • Multi-groove design on tread center contributed to snow-packing pillar can enhance snow performance.
  • Unique groove bottom design can grasp and embed ice/snow,  bringing out snow-packing pillars with limited displacement and deformation to upgrade snow performance.
  • 3D sipe design adopted on tread shoulder blocks can make block with less deformation, retain block stiffness and supply handling stability during driving.
  • Complete depth design on tread shoulder grooves(same as center grooves) can provide sufficient volume for accommodating snow to keep grip on deep snow.
  • Ice braking for SW-9 is 11.6% better than SW-8. Snow braking for SW-9 is 3.4% better than SW-8.
