The Primacy HP is Michelin’s Grand Touring Summer tire developed to provide longer tread life and lasting performance throughout the tire’s life, as well as better braking, steering control and handling on wet roads. The Primacy HP 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. While Primacy HP tires are designed to offer reliable traction in dry and wet conditions, they are not intended to be driven in near-freezing temperatures, through snow or on ice.
Primacy HP tires benefit from Michelin design innovations known as A.S.M. (Architecture, Sculpture and Materials) reflecting Michelin’s ability to focus simultaneously on three fundamental factors that determine a tire’s capabilities. Using their A.S.M. design method, Michelin can develop tires that combine an architecture that deforms more easily to optimize contact with the road, a tread design sculpture that remains rigid so more of the footprint contributes to performance, and unique tread compound materials precisely blended by Michelin’s mixing technology.
Primacy HP tires use a new generation Michelin tread compound molded into an asymmetric tread design that features large, linked shoulder blocks, notched intermediate ribs and a solid center rib to combine responsive handling and high-speed stability with traction and even treadwear. The Primacy HP tire’s structure includes twin steel belts reinforced by size-optimized BAZ Technology (spiral-wrapped Polyamide Banded At Zero degrees to tire rotation) to enhance ride quality while providing high-speed durability.
