Vibration after 19" aftermarket rims & tires
I know this topic is common on most forums but I just encounter it after replacing my stock 16" inch wheels off my 97 LS4 with 19" RPM r505's. My new wheels are 19x8.5 and 19x9.5 and they look sweet.
Anyway as soon as I drove away I felt some serious vibration at 50mph and up. After a long afternoon of google searching and a bunch of mis-information people were talking about everything under the sun was causing the vibration. Then, I found out something new. these wheels like most wheels that are designed to fit a variety of vehicles, come in different lug patterns. They actually have a hub "gap" or in my case 6.5mm of play in any direction when you place them on the lugs and tighten them. So they must of not have been perfectly centered on lugs when they mounted them. I think this is called "lug-centric"? I read something about being hub centric and kept searching.
So I found this website http://www.justforwheels.com/hub-centric-rings.jsp
which I believed explains hub rings in detail and was a very good source of information. I spoke to a person there and they confirmed that not having these hub rings was the cause for my vibration. Upset that the wheel shop didn't know about these or didn't put them on my wheels, I called the manufacturer. They told me the shop was dumb and shouldn't got these hub rings for me at the time they order my wheels. The wheel company "speedy wheels" was so nice they told me they would give me the hub rings free, so I stopped by and picked them up.
Needless to say after I put the wheels on with the hub Rings all the vibration was gone and my baby is as smooth as butter once again.
the rings are: 73mm to 60mm fitment in case anyone needs some.

Sometimes if you torque the wheels on really well w.o hub rings it can help eliminate some of the vibration. It's kind of equivalent to cutting springs though. If you have the means to get the proper parts you should go that path. Glad to hear it all worked out.

Also on your wheels as previously stated I had same issue with correct hub centric rings - shop was over tightening...now I torque in the air and my LS runs smooth since.

I didnt know that about the emblems. Thanks for the info. I like the idea of matching the white, gotta find a pic first to see how it would look.
I found some clear signals for the front only 55 bucks

Yes I agree, excess overtightening is very detrimental to the car. I was told by a D1 driver that you can run without hub rings as long as the wheel is on very securely. I ran my car without hub rings for a few days without problems. Because of the alarming amount of vibration from the OP, trying to tighten on more would do more harm than good.
