Michelin Primacy Alpin PA3

The Primacy Alpin PA3 is a Michelin's Performance Winter tire developed to meet the needs of a variety of sporty coupes, sedans, crossover vehicles and SUVs. Michelin Primacy Alpin PA3 tires are designed to deliver improved wet braking and controlled maneuverability in the cold and snow. The Primacy Alpin PA3 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 tread 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 combine high-speed capability with ride comfort. The Primacy Alpin PA3 winter radials meet the industry's severe snow service requirements and are branded with the mountain/snowflake symbol. They feature blackwall styling and are available in selected H-speed rated 55- and 50-series sizes for 17" wheel diameters. Install Primacy Alpin PA3 tires in sets of four only. Vehicles should always be equipped with equivalent tires at all wheel positions. These winter 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.
