- With the All-Weather Dual Performance Compound, the Nokian WRG4 features longer-lasting tread life and draws inspiration from nature with its Centipede Siping - jagged 3D sipes on the center rib that resemble the legs of a centipede. The centipede sipes grip the surface to maximize biting edges while maintaining stable handling.
- The inner shoulder's fan-like rib pattern with functional tread blocks and Blade Grooves efficiently routes rain, snow and slush away from the contact surface. The sipes staggered at different angles provide effective longitudinal grip and acceleration grip on snow and the wide longitudinal grooves offer lateral grip. The winter grip is further enhanced by the block pattern that is shaped on the inner shoulder side of the center rib. It is partially equipped with hinges and sipes and the small, heavily siped tread blocks are grooved so that every other sipe is attached on the left and every other on the right.
