The CT578 Plus from Cosmo is a commercial tire that's designed for use on all positions of trucks and buses in long haul applications. A five rib tread pattern works with wide shoulders to improve handling and stability, and the CT578 Plus utilizes four wide grooves to drain water out of the tread for better traction, handling, and braking performance in wet weather.
