Bridgestone Americas has developed a new steer tire for long- and regional haul trucks. The Bridgestone R283A Ecopia tire is engineered to deliver 21% longer wear life and a 3% better rolling resistance than its predecessor, the company said.
New tire incorporates Bridgestone’s IntelliShape sidewall that reduces bead filler volume, reduces tire weight and minimizes rolling resistance for enhanced fuel efficiency, the company said. It also utilizes a new tread compound that works with Bridgestone’s patented NanoPro-Tech polymer technology designed to limit energy loss and contribute to longer wear life. A lower cap/base junction delays exposure to the base compound, reducing the occurrence of irregular wear and allowing tires to travel further between retreading and replacement, the company said.
The R283A Ecopia also includes Bridgestone’s proprietary shoulder design engineered to optimize the footprint for longer, more even wear and a Fuel Saver sidewall to reduce heat generation and energy loss. A four rib design enhances tread stiffness for improved fuel economy and optimized tread depth and width maximizes tread volume for long original life and lower treadwear cost per mile, the company said.
The R283A Ecopia steer tire is EPA SmartWay Verified and California Air Resources Board (CARB) compliant, Bridgestone said. It is available in sizes 295/75R22.5 and 11R24.5 and will be available in 285/75R24.5 and 11R22.5 sizes in April.
