The Long Empty Run Specialist
• Truck designs that have a counterbalance effect when the truck runs empty – CL-I or CL-II will transfer the trucks weight directly onto the drive tire without the help of counterbalancing cargo.
• In some CL-I and CL-II trucks the load wheels and tires act like pivot points, resulting in a much higher load on the drive tire when the truck is unloaded.
• If a truck is empty or has a long distance to travel it will operate at a much higher speed.
• A combination of heavy load and high speed causes the compound to heat up. The long operating distance pushes the tire to run continuously without time to cool down – eventually melting the polyurethane..
• Use a high dynamic compound (low rolling resistance) that won’t generate heat beyond the melting point of the compound.
• Cushothane® XL-AC™ for all CL-I and CL-II tires.
