They're not the really new type as they've no reflector hole on them.
Not all new Skyways have the little hole for the reflector I think that was only done for OEM wheels i.e. Tuff IIs destined for manufacturers to put on their completes.
Are they sealed bearing if so they are new ones. Does the rear have a riveted hub, if so then they are old ones.
They look like newish ones as the rear does look like it has a plastic hub.
