New Pattern Design for Optimum tread stiffness and Optimum stud hole allocation
New Stud Model
Star-shaped stud chip & flange design improve edge effect. It improves performance on ice and good stud retention. New stud model and optimum stud hole allocation helps improvement on ice performance and less noise made with tread pattern and stud.
New stud hole shape and allocation
Installing the new stud hole shape makes less crevice at the stud hole and stud. By lifting the rate of thick tread contraction it makes tread compound hold the stud tightly.
High Density richly reinforced and flexible polymer
Delivering optimum tread stiffness. It stabilises driving on dry roads.
Silica
Silica improves performance on snow & wet.
