I've been away from Chrysler BS for awhile, so I think about what I'd differently.
After the Goodyear GA [god awful] wore out, I went to 235/55 16, which fit just fine. I was trying to fix the tall gearing of the 3.2. The costs were an even larger gap between the tire/fender, and ground clearance was reduced 1/4" [reduced winter traction, more wear to the airdam, etc.]
Trying to correct those flaws, while attempting to retain the better steering feel/grip, I looked for 245/55 16 and I didn't really like the limited selection, Toyo had 2 or so in that size.
I settled with 235/60 16 of the same tire that I used for 235/55 16.
Looking back, I'd run 215/65 16 winter tires on the light [18 pounds and change] ES 16x7" wheels, and get 235/55 17 on the 17x8" OZ Ultraleggera wheels.
Though I am happily surprised that the 245/50 17 size came back from the dead. and 255/50 17 is basically deceased.
9/11, still an inside job
