Leave the tyres off, it'll make life easier. Putting on tyres don't actually contact the rim so paint should be fine.
Rub down with 1000, prime, leave to dry.
Rattle can matt black, carefully mask off your valves.
Either rattle the lime lip on top or with semi tacky masking tape ( stick it to your shirt a few times to make it low tack)
Or get a pin striping brush, steady hand and setup a lazy suzy depends what you want.
Top tip wouldn't bother rubbing between prime and paint.
2nd one would be warm your wheel with a hair dryer, warm your paint under a hot tap prior to spraying...
Rest is just practice.
Good luck
