Shocks and tires held as constant, supporting info if you have it.

 

i would assume the weight would dampen out vibrations more effectivly on a heavier wheel.



the key word here is "assume"

 

ABSOLUTELY NOT.





Imagine that you have a ping pong ball and a basketball connected to each other via a spring. If you push the ping pong ball by two inches, it's not going to affect the basketball very much. Now if you exchange that ping pong ball for a medicine ball, moving the medicine ball two inches is going to move the basketball a heap.



If that makes sense to you, exchange the basketball for your car body and the other balls are your wheels of varying weights.



I could rattle on and on about this, but for the sake of brevity, google 'unsprung vs sprung weight' and have a read.
