Launched in 2022, the Dunlop Sportmax Roadsmart IV is a top-performing sport touring tyre. The rubber compound has been refined and the tread pattern optimised, offering remarkable grip on wet roads and increased durability. The Sportmax Roadsmart IV benefits from Dunlop's JointLess Tread (JLT) and Multi-Tread (MT) technologies used in competition, which help reduce wear and dampen road noise. The tyre is more durable and resistant; the carcass construction techniques (DFF and CTCS) ensure improved handling and stability.
