High speed vibrations Options

[Coligion]

My car just hit 96k miles, but this high speed vibration issue has always been a problem. When going over 55 mph, I'll get a ton of vibration from the steering wheel. I do have aftermarket wheels/tires. When I first bouht the wheels, I did not have centering rings and believed that would solve the problem. No dice. Even after getting the correct sized rings the car still vibrates. Before getting the rings, I did have the alignment and the wheels balanced. I wouldn't think inserting plastic hub-rings--in the center of wheel--could offset the balance, right? The shock/struts are relatively new, so it couldn't be that. Also, the car had this vibration problem even with the original wheels....Any helpful advice is appreciated.

i definitely thought of rebalancing, but it doesn't really explain why the steering wheel vibrates on some roads, while on others is smooth. if the wheel really did needed rebalance, wouldn't it vibrate on all roads?

Mstoochn asks, "...does it calm down at a certain speed bracket?" On the road that my steering wheel does vibrate, it feels smooth when im going 65. When i hit 70, it starts to vibrate. Then anything above 70 just increase the amount of vibration.
