I'm a big tiltrotor advocate but they aren't really designed for that. Tiltrotor lifting surfaces (V-22 as a case study) are very small, and they would have space shuttle-tier glide ratios. The V-22 can't autorotate well either because the rotors are rather lightweight. Tiltrotors can't really do unpowered landings well, if at all, in most cases.
Tiltwings would probably do this much better, but at the cost of more difficult and dangerous vertical landings.
