Class 3 vehicle
US commercial vehicles are sorted into classes by gross vehicle weight rating, the maximum the vehicle is allowed to weigh fully loaded. Class 3 sits in the middle of the light-duty range and includes big work vans and heavier pickups.
PitPro says its tire system is built for Class 3 vehicles and smaller. In practice that means your family sedan, SUV and most delivery vans are in scope, while a semi truck is not.
