rim stuck on due to wheel stud

Ok here goes. I heard this weird sound coming from the passanger side tire. I stop and check it out and notice one wheel stud missing and one stud broken and the other 3 loose. I tightend up 2 but 1 wouldnt tighten. now my delemma is i cant get the tire off becuase the stud is stripped and i cant cut it off with out damaging the rim or drum. is there another way i can try to get this off.
