The Prometeon H02 Pro Trailer summer tyre was developed for trailers dedicated to long-distance journeys. Designed to enhance fleet efficiency and reduce operating costs, it features a novel tread pattern with four central grooves. This configuration increases tread rigidity and limits rolling resistance. Two grooves positioned on the shoulders reinforce steering precision while accelerating water evacuation, ensuring stability and safety. The channel design also optimises grip on wet roads and reduces pass-by noise, thus providing superior external acoustic comfort. Finally, small longitudinal openings inserted into the central grooves secure the trajectory and shorten braking distances, whatever the summer weather conditions. This tyre therefore represents a preferred solution for heavy-duty trailers covering long distances.
