The Bridgestone ER300 Turanza is a fuel efficient summer grand touring tire. These tires were made as original equipment tires for Mercedes Benz sedans but they can be used on a number of sedans and coupes as replacements. These tires provide combined handling, traction and comfort for wet and dry road conditions and of course cannot be driven in temperatures close to freezing where there is snow or ice on the surface. This tire has a summer tread compound and sports an asymmetric design. They feature large tread blocks with continuous circumferential ribs that provide traction on dry roads and responsive handling. It also features circumferential and lateral grooves that help to push water away from the footprint of the tire thereby enhancing the wet traction of the vehicle by reducing hydroplaning. Internally the tire’s structure features two steel belts reinforced by spirally wrapped nylon and aramid. This helps to stabilize the tread area and helps to provide the tires with their high speed capability and enhances their handling. These tires can be found with the Bridgestone Ecopia branding that signifies that they offer reduced tire rolling resistance to enhance the fuel economy of your car.
