You don't have to look that much further for a premium extreme weather studded winter tire than the Hakkapeliitta 7. Formerly the record holder for the fastest land speed on ice, the 7 has the patented Hakka Sipe pattern with its flexing zig-zag that basically pioneered winter tire sipe patterns. Even the studs are revolutionary with their trapezoidal shape and numerous biting edges. Underneath the studs are air pillows that reduce road noise and stud wear. Even in the dry, the tire handles well thanks to the stiffened center rib. Only the newer Hakkapellitta 8s can trump this tire, and both are only available here at Kal Tire.
