After it is welded the weld should be ground down so the bead is not proud of the surface.If it is left up as a bead,as it flexes it will crack at the junction of the bead and the original surface.On something like a truck frame,that is very important,with the flexing of the frames grossing 100,000 pounds.On something like a wheel it may not be an issue at all.I have a couple that I ground the outside down but left the bead on the inside.I also have some wheels that were redone by folks that didn't check the lug holes first,and found them wallowed out after painting.I used them on my own truck with the washers,been on there since the mid 90's.So far,so good.
