The Ecopia EP500 is a Grand Touring Summer tire developed by Bridgestone for BMW i3 and i8 electric cars. It is designed to reduce energy consumption, improve vehicle aerodynamics, and enhance vehicle range. The tire provides traction in both dry and wet conditions, but it is not suitable for near-freezing temperatures, snow, or ice. Bridgestone's ologic technology, which combines a large diameter tire with a narrow tread pattern, helps conserve energy and improve tire and vehicle aerodynamics. The unique appearance of the Ecopia EP500 features a summer tread compound molded into a four-rib asymmetric tread design, promoting grip in wet and dry conditions. The tire also has large outboard shoulder blocks and three circumferential grooves to enhance dry road traction and wet traction. Specific sizes with Ecopia technology are clearly labeled.
