The Primacy HP is Michelin's Grand Touring Summer tyre developed to provide longer tread life and lasting performance throughout the tyre's life, as well as better braking, steering control and handling on wet roads. While Primacy HP tyres are designed to offer reliable traction in dry and wet conditions for drivers of luxury sport sedans, they are not intended to be driven in near-freezing temperatures, through snow or on ice.
Primacy HP tyres benefit from Michelin design innovations known as A.S.M. (Architecture, Sculpture and Materials) that reflect Michelin's ability to focus simultaneously on three fundamental factors that determine a tyre's capabilities. Using their A.S.M. design method, Michelin can develop tyres 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 tyres 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 tyre's structure includes twin steel belts reinforced by size-optimized BAZ Technology (spiral-wrapped Polyamide Banded At Zero degrees to tyre rotation) to enhance ride quality while providing high-speed durability.
