They still slip back and forth making the holes even bigger while damaging the stud threads. The hole in the rims are counter sunk so the tapered lugs nuts will clamp them into position tightly. This done because of the torque that these experience in operation. Just using washers the rims will slip under torque.
It is best to bite the bullet and get new or a reclaimed (used good) rim. Just trying to redneck patch things is just prolonging the problem while causing more damage. But at least it is not as bad as the mower blade that I seen duct taped on.
