here's what i'm talking about. after I painted my calipers and hubs I took my wheel off and you can see the build up from the paint. well, I didn't brush it down flat and when I reinstalled my wheels I had slight vibrations driving down the road. came back home and took a brush to the hub...slapped the wheels back on and the vibrations was gone. not saying your issue is the same but I would give it a try since those are new wheels
