The Primacy MXM4 is Michelin's Grand Touring All-Season tire developed for luxury sedan and coupe drivers looking to combine all-weather handling and traction with good noise and ride comfort. Most Primacy MXM4 tires meet Michelin's Green X standard* for eco-focused manufacturing and low rolling resistance, and confirms the tire's contribution to reducing vehicle fuel consumption, emission of CO2 gases and improving sustainability through conservation of natural resources. The Primacy MXM4 is designed to blend a quiet, comfortable ride, responsive handling and enhanced fuel efficiency with year-round all-season traction, even in light snow.
The Primacy MXM4 features Michelin's first use of their patented sunflower oil-enriched Helio Compound technology in an all-season tire 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 an asymmetric tread design featuring a European handling profile with rounder shoulders that are designed to provide progressive, predictable cornering. Circumferential grooves evacuate water out from under the tire's footprint to reduce hydroplaning while Michelin's 3-D Variable Thickness Sipe Technology provides additional biting edges to enhance wet and wintertime traction.
The Primacy MXM4 was developed with Michelin Comfort Control Technology using computer-optimized design and precision manufacturing methods to reduce vibration and road noise. The tire's internal structure includes twin steel belts reinforced by Michelin's BAZ (Banded At Zero) spiral-wrapped polyamide cord that stabilizes the tread area to enhance treadwear, handling and high-speed capability. The Primacy MXM4 features a polyester cord body to provide a smooth ride.
