Riding 1 wheel up on a ramp, and suspending the other wheel (for changing a flat, repacking bearings, whatever)....isn't that most likely overloading that 1 wheel/tire?
Sure it's not as bad as driving on 1 tire, but that's a lot of weight, for what could be a significant amount of time.
I would rather have an actual jack and left at the frame, than risk damage to a tire like that.
