So, as the title says, I'm looking for a set of wheels I can put upon my drill motors with a 3/8 UNF nut, or M10, if that's even the same. Either way...

I need the wheels to be at least 13.5 to 14 cm in diameter. If there's tire tread on it as well, then that's fine, if not, that's fine too, I can just cut up some cheap rubberised yoga mats.

If possible, please give me a nudge and I'll reply as soon as possible.
