The Pilot Sport 4 SUV is Michelin's Street/Sport Truck Summer tire developed for the drivers of powerful and performance-focused crossovers and SUVs. The Pilot Sport 4 SUV is optimized for enhanced comfort and low noise and designed to deliver outstanding grip in warm, wet and dry conditions. Like all Street/Sport Truck Summer tires, it is not intended to be serviced, stored, nor driven in near- and below-freezing temperatures, through snow or on ice.A summer-focused tread compound utilizes functional elastomers and thin silica for improved traction in wet and dry conditions and is molded into a performance-oriented, asymmetric pattern. High pattern stiffness and a rigid design help provide strong lateral grip in the dry, and the optimized notches enhance dry braking performance. The inboard side of the tread features a wider circumferential groove and greater pitch count for enhanced wet traction, while the deep, straight channels help evacuate water from the contact patch to improve hydroplaning resistance.The internal construction of the Pilot Sport 4 SUV consists of a high-density, polyester casing that provides a robust and durable structure and supports two wide, steel belts. An aramid and nylon hybrid reinforcement ply enhances driving precision and high-speed capability.Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle.Flexing of the specialized rubber compounds used in Street/Sport Truck Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage. Tires exhibiting compound cracking must be replaced.
