A quad tiltrotor aircraft (10, 100, 200) has a longitudinally extending fuselage (12, 312) with forward and aft stations (14, 314; 16, 318). A forward wing (18, 320) having first and second outboard ends extends laterally from the forward station (14, 314). An aft wing (20, 324) having first and second outboard ends extends laterally from the aft station (16, 318). First and second forward rotors (26a, 26b, 112a, 112b, 212a, 212b, 330a, 330b) are respectively coupled proximate the first and second outboard ends of the forward wing (18, 320) and are tiltable relative to the forward wing (18, 320) between vertical lift and forward thrust orientations. First and second aft rotors (36a, 36b, 120a, 120b, 220a, 220b, 342a, 342b) are respectively coupled proximate the first and second outboard ends of the aft wing (20, 324) and are tiltable relative to the aft wing (20, 324) between vertical lift and forward thrust orientations. The forward rotors (26a, 26b, 112a, 112b, 212a, 212b, 330a, 330b) are higher disk-loading rotors than the aft rotors (36a, 36b, 120a, 120b, 220a, 220b, 342a, 342b). The aft rotors (36a, 36b, 120a, 120b, 220a, 220b, 342a, 342b) are foldable in the forward flight mode to provide extended range for the quad tiltrotor aircraft (10, 100, 200).
