With most wheels I sell, the general rule is cars come with hub centering rings while truck rims rarely do.. If I try to order rings for truck wheels, they are usually called hub spacers while cars are referred to as hubcentric rings. In any case, all of our wheels come with new lug nuts
as for the small hub compared to a large wheel.. I often wonder this but 95% of the wheels we balance are centered using a cone through the hub, not the lug holes. There are plates that can be used to center on lug nuts.. But they are only used on wheels that are at risk of getting scratched or have holes too small/too large for one of the centering cones (very rare)
