Nankang Ice Activa Grip 2 ( 225/50 R17 98T XL, studded, with rim protection (MFS) )

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 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.
