P4 Four Seasons tyre is a Standard Touring All-Season tyre developed for the drivers of coupes, sedans, minivans, crossover vehicles and small SUVs. It is designed to perform in all four seasons by blending ride comfort, low noise and high mileage with traction on wet roads and in light snow. The tread compound is moulded into a symmetric pattern that features a continuous centre rib and independent tread blocks (185mm section width sizes feature a single circumferential centre groove and no centre rib) that employ computer-designed siping to combine handling on dry roads with traction on wet roads and in light snow. It features a computer-aided design (CAD) optimized tread profile with an internal structure that includes twin steel belts reinforced by spirally wrapped nylon to combine good wear with ride quality and durability. Key Features and Benefits: Pirelli P4 Four Seasons tyre features a silica-rich tread compound to reduce rolling resistance and enhance foul-weather traction. CAD optimized tread profile and compound for low treadwear. Two central circumferential grooves and numerous angled grooves help water escape from between the tyre and the road to reduce the risk of hydroplaning. Variable angle grooves ensure higher mechanical grip. Polyester cord body plies combine strength with ride comfort. Two central longitudinal grooves provide maximum water expulsion. Reinforced shoulders provide enhanced stability and even wear. Computer designed siping for maximum traction in wet and snow conditions. Designed to provide ultimate ride comfort, reduced noise, high mileage with excellent traction in wet weather and snow conditions.
