wheelliners & hubcovers

Wheel "rings" or wheel "liners" have already been discussed as they were used in a combination set with a Super Single wheel.
Yet they can also be used completely apart, e.g. in the rear wheels ...and this in several depths.
These rings usually have the LR wheel assembly system and exist in "open" form, without hub cover, OR "closed", with hub cover.
The hub covers are also available separately or in combination with these liners (see also: "America Simulator").
