Michelin Primacy Alpin PA3 ZP

The Primacy Alpin PA3 ZP (Zero Pressure) is Michelin's Performance Winter / Snow run-flat tire developed to meet the wintertime driving needs of MINI Coopers fitted with Original Equipment run-flat tires. The Primacy Alpin PA3 ZP offers temporary extended mobility (up to 50 miles at 50 mph) in the event a puncture results in complete tire pressure loss. Michelin Primacy Alpin PA3 ZP tires are designed to maintain good braking and maneuverability in cold, wet and wintry conditions. The Primacy Alpin PA3 ZP features a sunflower oil-enriched Helio Compound to increase traction at low temperatures for improved braking and handling in the wet, as well as better overall performance in the snow. The Helio compound is molded into a directional tread design featuring independent shoulder and intermediate blocks combined with a continuous center rib to help maintain traction in dry, wet and wintry conditions. Michelin's StabiliGrip™ technology with bidirectional auto blocking sipes and variable geometry also provides more biting edges to improve acceleration and handling in snow and on ice. The tire's internal structure includes a polyester cord body under twin steel belts that are reinforced by Michelin''''s BAZ technology, where polyamide cord is spirally Banded At Zero degrees to the direction of travel to provide high-speed durability. Sidewall reinforcements using low hysteresis rubber provide self-supporting strength that combats sidewall damage to allow temporary zero-pressure driving. A special bead design helps tires stay securely seated on conventional rims. The Primacy Alpin PA3 ZP winter / snow radials meet the industry''''s severe snow service requirements and are branded with the mountain/snowflake symbol. The Primacy Alpin PA3 ZP tires feature winter wear indicators to identify when wear prevents the remaining tread depth from providing beneficial snow performance. Install Primacy Alpin PA3 ZP tires in sets of four only. Vehicles should always be equipped with equivalent tires at all wheel positions. These winter / snow tires, due to their exceptional snow and ice traction provided by their unique tread compounds, must be used in sets of four to help ensure proper vehicle control.
