[Chrysler300] Re: Thinner rims?

[Tony Rinaldi <awrdoc@xxxxxxxxx>]

Hi John & all,

Don't have a new wheel to mic since I have tires mounted on them. Could only
mic the old wheels right now.

If you look at the photos on my homepage, the photo with the ruler show the
thicker bead edge on the new wheel and the photo that compares the faces of
a 300-Ç wheel vs the new wheels, you can see that the lug hole areas are
reinforced and the center of the wheel is thicker on the new wheels. That is
why you can't use center dog dish caps with them.

John, I am sending you larger photos so you can see much more better!!!

Anyone else who wants the larger pictures (300 Yahoo site will not allow for
jpgs) let met know and I will send them to you.

Tony
