Continental has launched the HDL2 Eco Plus trailer tire in size 445/50R22.5. Designed with fuel efficiency and long haul mileage in mind, the HDL2 Eco Plus is easy to check for inflation and offers significant reductions in rolling resistance, according to Continental. Additional features include 27/32nds of tread depth, a closed shoulder, and a three-dimensional sipe in the center of each tread block that allows flexibility, but couples the groove under compression for increased strength.
