The Direzza DZ101 (di-rez'-za) is Dunlop's Ultra High Performance Summer tire for the drivers of sport compact cars. The Direzza shares its name with Dunlop's Japan GT Championship (JGTC) racing tires, and was developed to provide crisp and responsive handling in both wet and dry conditions, however it is not intended to be driven in near-freezing conditions, through snow or on ice.

On the outside, the Direzza DZ101 features Dunlop's specially formulated Silicarbon Matrix tread compound (combines silica and carbon black) to enhance grip in the wet without surrendering traction in the dry. The compound is molded into a directional tread design featuring rigid shoulder blocks and two wide, straight tread channels with long, oblique grooves to combine responsive handling, stable cornering and hydroplaning resistance.

Internally, the Direzza DZ101 features twin steel belts reinforced by Dunlop's Jointless Band (JLB) spiral-wound cap ply to stabilize the tread area enhancing handling and high-speed capability. A polyester cord body enhances ride quality while Max Flange Shields help resist rim damage due to accidental curbing.
