The Winter Snowcontrol Serie 3 Run Flat is Pirelli’s Performance Winter / Snow run-flat tire designed for coupes and sedans to provide a high level of security on cold, dry, wet and wintry surfaces. Winter Snowcontrol Serie 3 Run Flat tires feature Pirelli’s Self-Supporting Run Flat Technology that enhances safety and convenience by providing temporary extended mobility in the event a puncture allows complete loss of air pressure. Pirelli’s Self-Supporting Run Flat Technology allows tires to literally “run flat” for up to 50 miles at 50 mph (80 km at 80 km/h) unless otherwise specified by the vehicle manufacturer for Original Equipment tires. The Pirelli Ecoimpact* icons on the sidewalls of Winter Snowcontrol Serie 3 Run Flat tires highlight their contribution to the environment with regards to energy efficiency, clean air and low noise.
The Winter Snowcontrol Serie 3 Run Flat uses a second-generation silica-enhanced winter tread compound that increases rubber flexibility in cold temperatures. This compound is molded into a directional tread design blending cold weather traction and handling. Rounded shoulder blocks and interlocking center blocks featuring Pirelli’s Interactive Brickwork Siping where the sipes create a brickwork pattern increase both lateral and longitudinal stability while providing more biting edges to increase snow traction, ride comfort and noise quality. Two wide circumferential channels and numerous lateral grooves help channel water and slush to the sides to enhance hydroplaning resistance and wet traction. The tire’s internal structure includes twin steel belts reinforced by spirally wrapped polyamide that enhances thermal stability and makes the tires less sensitive to changes in road and air temperatures.
Snow Wear Indicators (SWI) in the tread design identify when the remaining tread depth begins to deliver diminishing snow performance (in addition to the bottom-of-the-groove treadwear bars that indicate the tire is completely worn out at 2/32″ of remaining tread depth). In the case of the Winter Snowcontrol Serie 3 Run Flat, notches of selected center rib blocks wear smooth when approximately 5/32″ of tread depth remains.
Pirelli’s extended mobility solution is made possible by their MIRS computer-controlled robotized manufacturing system, a production process that assures consistency in the application of the additional sidewall reinforcements that provide the self-supporting run-flat capability.
Winter Snowcontrol Serie 3 Run Flat winter / snow tires meet the industry’s severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.
Install Pirelli Winter Snowcontrol Serie 3 Run Flat tires in sets of four only.
Due to the traction capabilities of the Winter Snowcontrol Serie 3 Run Flat tires, Pirelli recommends using them only in sets of four to provide the best handling characteristics and tire performance.
