Highway Rib Summer light truck tires are for drivers who want a combination of heavy-duty load capacity, even wear and low noise along with traction on dry and wet roads. Sometimes used as Original Equipment (O.E.) on medium and heavy-duty 2WD trucks, vans and pickups, Highway Rib Summer tires are not intended to be driven in near-freezing temperatures, through snow or on ice.O.E. Highway Rib Summer light truck tires are typically purchased as direct replacements for worn-out pairs/sets of the vehicle's original tires. They can also be used for other vehicle applications in complete sets of four or axle pairs if available in an appropriate size, load range and speed rating to match the existing O.E. tires' performance category and specifications.
