<VV> Fwd: [FC] 17" or 18" wheels on an FC

[ScottyGrover at aol.com]

Question:--given the same O.D. of the tire/wheel assembly, how much heavier 
 is a setup with mostly metal over one with more of its' diameter being  
rubber?

P.S. I am old enough to remember wheels being 15" or 16".  They seemed  
adequate for their day.  Then wheel sizes were reduced to 14", then 13"  
requiring the development of disc brakes because the drums became too small for  
effective braking. I still don't understand WHY  wheel sizes were  reduced so 
much--I suspect it was mostly for styling.

Another disadvantage with the large wheels and tires is  excessive and
premature wear to the suspension and steering components. I  surmise this is
due to the extra weight. Those big wheels and tires are a  lot of weight to
hang out there on the end of the control arms. Also so  much unsprung weight
has a huge impact on ride quality, handling and  braking performance! Since
I started working at a Chrysler dealer with all  the 300 and Charger models,
which seem to be a favorite for this "upgrade",  I have seen ball joints,
tie rods, control arms and other components torn  up in less than 20,000
miles!
