Greatly elevated performance on ice and snow than the predecessor, in terms of braking, acceleration, and driving stability. The performance is tested and proven in the top-rated proving ground of Finland.

• Being certified by the Overrun studs test results, SW-9 has the utmost ice grip capability with more number of studs, but applies to the least damage on road surface.
• Optimized stud allocation enables each stud to output the highest efficiency against road surface, to enhance traction on icy roads and upgrade ice performance.
• The exclusively developed triangle-shaped stud carbide has proven to offer greater ice friction than normal round shape stud carbide, to improve ice performance.
• Multi-bars on tread center grooves, contributing to snow-packing pillars, enhances 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.
• Enlarged depth on tread shoulder grooves can provide sufficient volume for accommodating snow to keep grip on deep snow.
