Designed to help reduce environmental impact, P4 Four Seasons Plus tires combine ride comfort, low noise and reduced rolling resistance with long life and four-season traction on dry, wet and wintry roads, even in light snow.Pirelli P4 Four Seasons Plus tires feature a silica-rich tread compound made possible through use of innovative materials and processing methods to reduce rolling resistance while enhancing foul-weather traction.
