Bridgestone Bandag Tire Solutions announced Thursday, March 25, in Louisville, Ky., that it has refined its Bridgestone-brand R287A steer tire for regional and long-haul applications. The new tire – SmartWay-approved by the U.S. Environmental Protection Agency and California Air Resources Board-compliant – has a refined side groove structure designed to act as a shock absorber to help prevent shoulder edge wear from spreading to the ribs; the groove’s inside is designed to prevent stress cracking. An equalizer rib promotes uniform rib wear and higher removal mileage by fighting initiation and spread of rib edge wear. The R287A – which has a 16/32-inch tread depth – includes a cap compound designed to fight irregular wear, wear slowly and run cooler for additional tread life. A base compound shields the casing from damaging tread heat for enhanced retreadability.
