Lug nut bolt broke while trying to get tire off how do you remove it?

if broken stud is on disk, just knock broken peice out with a hamme. to reinstall place new one thru hole, using some washers as packing, attach wheel nut and screw tight to draw new stud thru hole until seated. then remove wheel nut and packing, if broken stud is in a brake drum, u need to remove the brake drum. then proceed same as for a disk
