The tires are directional Copper ZEON 2XS (mileage unknown) that appear very aggressive and this is hopefully the reason for the noise.

I took all of the following readings of our three vehicles at ear level between the driver and passenger (above the console) and the results are as follows:

2014 KIA Cadenza (40,000 miles on tires) = 64dB
2008 Dodge RAM 1500 4 wheel drive pickup (aggressive tires) = 70dB
2006 Crossfire Limited Coupe = 78db!

I expected the Crossfire to be considerably louder than the Cadenza but not to be louder than our Hemi pickup. Most of the noise in the Crossfire is coming from the back. In fact, if I put the meter in the back it reads well into the upper 80's.

When time permits I am going to put a new set of Hankook Ventus S1 noble on as Tirerack.com rates them as very quiet. Will report the new, and hopefully better, sound results after installation.
