Nitto NT555 G2 Tires (305/35ZR20 107W XL)

The NT555 G2 is Nitto’s next-generation Ultra High-Performance Summer tire, developed for drivers of muscle cars, sports cars, performance coupes, and sedans, seeking optimal dry and wet traction in a true grip-focused tire. Like all summer tires, the NT555 G2 is not intended to be driven, stored, or serviced in near- or below-freezing temperatures, through snow, or on ice.

The Nitto NT555 G2’s silica-reinforced high-stiffness compound is molded into a directional tread pattern, featuring large, tapered tread blocks for optimum dry grip. Two circumferential solid ribs at the tire’s center provide rigidity for straight-line stability during hard braking and acceleration, while reinforced shoulder blocks offer satisfying grip and cornering in both dry and wet conditions. Four wide circumferential grooves allow water to flow through the tread to lateral notches for water evacuation and hydroplaning resistance.

The internal construction of the Nitto NT555 G2 consists of a two-ply polyester casing for flexibility and stability. Its two wide steel belts are reinforced by 2 nylon cap plies for added durability and high-speed support.

Note: Ultra High-Performance Summer 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 Ultra High-Performance 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.
