Pirelli P4 Four Seasons Plus. FEATURES AND BENEFITS: All weather traction; Fuel efficient drive; Longer lasting tread life; Enhanced driving durability; Road vibration free drive; Precise steering responsiveness; . OVERVIEW: The Pirelli P4 Four Seasons Plus is a touring, all season tire manufactured for passenger vehicles and SUVs. Pirelli offers a 90,000 mile treadwear warranty.The tire's special high silica compound provides superb all weather traction. Its variable angle grooves increase the dry, wet and winter weather road gripping ability by ensuring better road grip all year. The silica-enriched compound stays flexible even in colder temperatures and it maintains its road gripping ability. The tread pattern's center area features two wide circumferential grooves that increase the wet weather traction and actively avoid hydroplaning with their water and slush evacuating ability. The better road gripping ability and traction allow a safer driving experience.The silica-enhanced tire compound ensures a more fuel efficient and environmentally friendly drive. It lowers the rolling resistance, which determines how much energy the vehicle needs to maintain motion, due to the better all weather traction. This decreases the vehicle's fuel consumption and CO2 emissions significantly, making the tire more energy conscious. The reduced rolling resistance also slows the tread wear down, by easing the pressure off of the tread. Furthermore, the optimized tire profile and reinforced shoulder design extend the tire life by preventing uneven wear. They equally distribute the driving pressure across the tread area and extend the tire's usability and life.The model's internal structure features twin steel belts reinforced with spirally wrapped nylon and a polyester cord body. This, along with the optimized casing profile, improves the driving durability and comfort levels. It closely follows the road surface which reduces the road vibrations created during the drive, and the maintained constant road contact lowers the road vibrations felt by the passengers. The inner construction reinforces the tire against the driving pressure affecting it. The model does not deform under any circumstance and it maintains the optimal tire shape to ensure excellent performing capability.The P4 Four Seasons Plus is easy to control in all weather. The tread pattern and the high silica compound maintain contact between the tire and the road at all times, which upgrades the steering responsiveness and driving stability. Together, the better stability against the driving pressure and the precise and quick steering responsiveness to the driver's commands offer an improved driving experience. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
