The Bridgestone R284 Ecopia tire, a SmartWay verified steer tire, is designed for improved fuel economy and enhanced treadwear. Engineered for performance in long-haul and regional service, the tire features an innovative tread compound for long wear life and patented NanoPro-Tech polymer technology for a 5 percent improvement in rolling resistance compared to the Ecopia R283A steer tire. An IntelliShape sidewall is designed to reduce tire weight and minimize rolling resistance. In addition, the proprietary Fuel Saver Sidewall compound works with the NanoPro-Tech polymer technology to reduce energy loss, ultimately improving fuel economy.
