For rims I use the Adams Wheel Woolies, they're slightly different sizes than the standard Woolies. They don't make them any more but you can still find them for sale. I'm not talking the ones with the bent neck, this is the regular 3 pack.
Tires, Tuf Shine brush
I have the Auto Finesse boars hair brushes for getting in rim lug nuts and small places. They're not cheap @ $40 for 2 brushes, but they work great.
