Michelin Primacy MXM4 235/55R18 100H

Precision Wet Braking. Sunflower Oil Helio Compound. Grand Touring Refinement. The Michelin Primacy MXM4 235/55R18 100H.

For drivers of luxury sedans, premium crossovers, and performance-oriented coupes running 18-inch wheels who demand the absolute best in all-season touring performance — the Michelin Primacy MXM4 235/55R18 100H is the tire that delivers on every front. Developed to Michelin’s most exacting grand touring standards, this tire has earned its place as original equipment on premium vehicles from Volvo, Acura, Mercedes-Benz, and Audi — brands whose engineering teams accept nothing less than the highest tire performance standards available.

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, confirming the tire’s contribution to reducing vehicle fuel consumption, emission of CO2 gases and improving sustainability. 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 numbers back this up — the Michelin Primacy MXM4 stops up to 29 feet shorter in wet conditions than a leading competitor — a real-world safety advantage that no specification sheet alone can fully convey.

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.

Built with a European-style handling profile for excellent handling and control, the Michelin Primacy MXM4 tire is a great choice for your premium vehicle. A sunflower oil additive in the tread compound helps provide extra grip and braking power in cold and wet conditions, while the tread itself features elements that lock together to provide more traction when needed.

Real Michelin Primacy MXM4 drivers confirm this performance: “These all season MXM4 tires are great. I’ve gotten these tires early 2025 and it’s been over a year and over 20,000 miles driven with these — all 4 tires still intact. Rain or shine and I’ve run into my share of potholes. These have been the best performing tires for me and comfort level is superb. Will forever re-purchase. Worth it!!!”

Backed by the Michelin Promise Plan — a 60-day satisfaction guarantee, roadside assistance, and a treadwear warranty of up to 55,000 miles — this is the premium all-season tire investment that pays back every mile of its life.
