The ones I’m use to seeing is there are fingers that grab into the rim where the wheel weights go. The balancing machine uses a big nut in the center hole of the rim,I doubt you'll find any tire place that can mount new tires on those rims - most tire mounting machines use the center hole on a conventional rim to hold the rim in place while the tire is put on. This, along with the overall condition, is reason enough to scrap the running gear and replace it with a more modern axle and rims.
