I don't think it is tar, which is why tar removers aren't touching it. It's more likely carbonised bits of brake pad material.
When you jam the brakes on, the top surface of the pads get super-heated and sloughed off by the friction... fly outwards and land, still baking hot, onto your rims. They then embed themselves into the surface and just stick there, half-melted and half bonded to the lacquer.. They won't come off easy.
The pieces also then carry on corroding acidly.. (being metal mostly, now that asbestos has been banned) so they'll pit and stain the lacquer if you leave them there.
So.. seal the wheels as that will provide a barrier to the pieces in the first place.. and also remove any new build up regularly as it's not nice stuff.
No bullets for Chaingun..
