Bridgestone Commercial Solutions announced two new Bridgestone brand tires for heavy-duty urban use. The Greatec M845 wide-base radial and M860A high-scrub all-position radial are designed for the stop-and-go driving, oil and chemical residue and potholes that city drivers face. The new design helps prolong tire life and retreadability while keeping the tire performing at its highest levels, according to Bridgestone.
