The computer optimized symmetric tread pattern and the durable all season tire compound improve the dry, wet and winter weather road gripping ability. The compound keeps its rubber flexibility throughout the year, including in winter weather, and it offers a durable performance. The tread elements upgrade the grip the tire has on the road surface and maintain it all year. The circumferential grooves prevent hydroplaning. They eliminate water and slush from beneath the tire's footprint and upgrade the wet and winter weather traction in the process.
