Matt, Have you checked your tire pressures lately? Dave is certainly much more of an expert than I when it comes to noises on DeLoreans and noises made by different kinds of tires on DeLoreans. I also had a hum/vibration with my car, usually in the 50 mph-70 mph range and almost always just on certain stretches of road. The worst was on raised (elevated roadway/overpasses) or grooved pavement. It still happens, but it was significantly reduced when I adjusted my tire pressure to the recommended pressures. The ride also improved noticeably.

This is what I'd suspect first.
