Outside of the silliness...you really can paint them any colours you wish. I'd imagine someone, somewhere knows precisely which units these are and who wears what, but the possibilities are pretty limitless.
With a gigantic territory, millions of soldiers, hundreds of different organizations, militias, etc.
Lately it does appear that the main forces of the PLA are heading in the direction of somewhat standardized digital-pattern camouflage, in a couple of different colour palettes.

PS: If you want white-walled tires..how about white-walled tank road wheels? Super. Gangster.
