Launched in 2022, the Dunlop Sportmax Roadsmart IV is a high-performance sport touring tire. The rubber compound has been improved, the tread pattern optimized, for exceptional grip on wet roads and better longevity. The Sportmax Roadsmart IV brilliantly inherits the JointLess Tread (JLT) and Multi-Tread (MT) technologies used by Dunlop in competition, for reduced wear and attenuated sound vibrations. The tire is more durable, for longer; the carcass construction techniques (DFF and CTCS) ensure better handling and stability.
