Built with Yokohama's Z.environment technology, the 101ZL is a long haul steer axle tire engineered to provide low rolling resistance and outstanding fuel economy at highway speeds, with improved casing durability. Combined with exceptional wet weather handling and improved wear resistance, the 101ZL is designed to run longer at lower cost. Constructed with inverted radius mold technology, the tire features a flatter tread profile that resists irregular wear, as well as advanced rubber compounding for more even carbon distribution and low rolling resistance. Its innovative casing is optimized to give the most even footprint possible.
