It makes the tire able to establish traction in every season despite the changing temperature and weather conditions. Combined with the directional tread pattern, the tire can dominate dry, wet and winter road conditions. The best thing about silica is that it maintains its flexibility when it's freezing cold. During the summer, on the other hand, it prevents pressure generated heat build-up. The tread pattern is densely populated with grooves, both circumferential and angled lateral, that prevent hydroplaning by dispersing water and slush.
