I had a flat yesterday morning, and was going to take my wifes' Xterra for new tires so I threw they flat into the back to get patched. To make a long story short, After i got home I noticed 4 or more marks on the inner side of my rim. Probably about 2" x 1". Are these stick on wheel weights or what?

Will it hurt if these have been removed and wheel weights have been added to the edge or bead of the tire?

If I had a camera I would post some pics but no camera. Any help would be appreciated. Oh by the way I have the 18" SE 5 or 6 spoke rims if anyone wanted to know.
