i'm in canada an i've got 16" alloys on my B2200. the centers have a larger diameter than that of the hub tabs, so they don't touch the tabs at all. If you look real close in the pic, you might see the tabs.
My dad's a mechanic and he said it'd be no problem driving without the tabs touching the rim because the lugnuts are the acorn type, which means they have a taper on the inward side that seats into the rim and told the wheel from shifting on the hub.
As far a police, i've never been pulled over, and i'm not sure if they'd even notice. you could always get a cap that covers the hub and tabs so they wouldn't even be able to see them.
