The Primacy 3 is Michelin’s Grand Touring Summer tire developed for luxury coupe and sedan drivers looking for warm-weather tires that combine good ride and low noise with better braking, steering control and handling on wet roads. Designed to enhance vehicle fuel efficiency and reduce CO2 gas emissions, Primacy 3 tires meet Michelin’s Green X standard* for low rolling resistance. While Primacy 3 tires are designed to offer reliable traction in dry and wet conditions in warm ambient temperatures, they are not intended to be driven in near-freezing temperatures, through snow or on ice.
Primacy 3 tires feature a new generation Michelin tread compound molded into a symmetric tread design that has a notched center rib flanked by independent intermediate ribs and large shoulder blocks to combine responsive handling and high-speed stability with traction and even treadwear. The Primacy 3 tire’s structure includes twin steel belts reinforced by size-optimized BAZ Technology (spirally-wrapped Polyamide Banded At Zero degrees to tire rotation) to enhance ride quality while providing high-speed durability.
