What PSI and CFM do I need for truck or SUV tires?

Larger truck, SUV and off-road tires benefit from a higher max PSI and stronger airflow (CFM/duty cycle) so the pump doesn't overheat or stall on big volumes. Heavy-duty VIAIR-style compressors in this list advertise 120–150 PSI and higher duty cycles for tires up to 33 inches and beyond, while compact cordless pumps are generally rated for top-offs on standard passenger tires rather than full inflation of large tires.
