The Turanza ER300 is Bridgestone's ecologically oriented Grand Touring tyre developed for Original Equipment use on Mercedes-Benz sedans, as well as can be used as replacements on other coupes and sedans. The Turanza ER300 is designed to combine traction, handling and comfort in dry and wet conditions. The Turanza ER300 molds a tread compound into an asymmetric tread design. Large tread blocks and continuous circumferential ribs provide responsive handling and traction on dry roads, while lateral and circumferential tread grooves help evacuate water from under the tyre's footprint to enhance wet traction and reduce hydroplaning. The tyre's internal structure includes twin steel belts reinforced by spiral wrapped aramid and nylon to stabilize the tread area to enhance handling and high-speed capability
