They are only $4.75 , which is a bargain if you take the time involved to make them into consideration. Dirtmodeler is a great company to order from fast delivery and very reasonable prices . As far as making them yourself it kind of depends on what materials you have on hand. It would probably be easier to find a set of rims that has the bead locks on them already. One idea that occurred to me is using paper to make them just cut it out and strengthen it with an epoxy then paint . I can't think of a cheaper way to do it hope this is helpful.
