These sipes appear often in the tread pattern and are full depth, meaning that they will not disappear as the tire wears. The tire's great traction is further enhanced, even in severe winter conditions, by the Snow Groove Technology. This technology gathers snow in the outer circumferential grooves of the tread to improve its traction. The snow packed in the tread grooves increase the grip as the snow provides better traction than the rubber on snowy roads, and this snow on snow traction makes the tire safer to drive.
