Like most drivers, commercial drivers want a tire that's built to last so that they don't need to frequently replace their tires. Knowing this, Cooper built the Pro Series LHD with a closed shoulder design that reduces uneven wear to help promote a longer tread life. Ideal for use on the drive axle of commercial trucks in long haul applications, the Pro Series LHD's wide footprint and deep tread depth promote even wear to further boost tread life. Stone ejectors within the tread force rocks, stones, water, and other unwanted materials out of the tire for consistent traction and to protect the casing from damage, and the Pro Series LHD is SmartWay verified thanks to a low rolling resistance design that enhances fuel efficiency and reduces CO2 emissions.
