Bear Claw Technology Bear Claw Technology and the anchor stud increase the braking and acceleration grip and wear resistance of the tyre. The Bear Claw is an innovation that keeps the stud perpendicular to the driving surface by optimally tensioning the tread block during braking. The multi-edged and sturdy anchor stud, on the other hand, boosts the longitudinal grip of the tyre upon acceleration and braking. Firm stud attachment guarantees reliable braking grip. The wide bottom flange of the stud supports it and boosts lateral grip. The especially strong bottom layer locks the stud firmly into the tread block and also improves the bare-road handling of the tyre.
