The Hankook DL11 tire is a long haul truck and bus radial. It has good all-season traction, low rolling resistance and excellent retreadability. The large open tread blocks are heavily siped for grip on icy roads. This tire offers a 4-groove tread pattern and zig-zag sipes and grooves for better wet and dry traction. There is also raised ribs between the blocks for better protection from the damage of stone drilling. Tread block stiffness is improved through the 3D sipes as well. The solid shoulder of the tire gives this tire exceptionally even wear and helps the tire run cooler.
