Generally the only wheels that are "factory" supplied with rim strips tend to be fairly high end ones, often what I call "component wheels". What I call "repair wheels" nearly never do.

Also every wheel I sell/install gets a trueness check and tweak as needed. The higher end wheels rarely need much prep work but repair grade ones nearly always need more before they are ready for sale. Bu, of course, this is one more reason to be able to touch and hold the product before exchanging money. Andy (whose shop sells Wheelmaster wheels from JBI and find they are usually mid grade at best)
