I have those in my wheel pack: https://beamng.com/resources/d-troxx-wheel-pack.185/ there are also similar vanilla wheels ingame
Nope, ones I posted have thinner, tapered spokes, visible bolts on the edge and they look a bit deeper to me, +they're less chrome-y.
I highly doubt the devs would waste their time adding wheels that look a lot like another wheel, and which you can barely tell the difference between them.
Some (proper official) 10 lug 5 hole steel wheels for bus and truck would be nice to see. I made some myself a couple of years ago, in a rather rubbish way of doing
The Pigeon has white steelies, so I think it'd just be a matter just resizing them for the appropriate cars
