What is the advantage of a 17" wheel over a 16" wheel?
I just noticed that on the 09 Dodge Caravan SXT
there is no option for 17", it comes only with the 16".
The Chrysler T&C Limited still has the option,
as did the 08 Caravan SXT.

Also noted is that the "sport suspension" is no longer
offered on either vehicle.

This is with 4.0 liter, 6 speed automatic transmission, TIA

17 inch rims use lower profile tires, theoretically providing better
handling, but at a definite reduction in ride compliance, and at a
significant hit in tire price.

I see that lower profile in some of the more extreme dia wheels, such
as the 20" seen on some performance vehicles.
With the Caravan/T&C there doesn't seem to be much difference,
as the two tire sizes are:
 225/65R16        16x6.5 rim
P225/65R17        17x6.5 rim

Out of the ordinry to have 2 different rolling diameters. You sure the
17 is not a 225-60?

They are within less than 1/4" in diameter that way.

I would go with the 16" wheels just for the fact that tires are going
to be easier to find for a 16" rim than 17", so they should be cheaper
too.  Unless you really like the looks of the 17s....

Visibly, it's very hard to see any difference.
They are the same profile.
225/65R16    vs    225/65R17

 Are you SURE????
The overall diameter on the 17 would be an inch higher than the 16.
Are they not 225 60 on the 17? Only 0.10" diameter difference that way
Or 225 70 16 and 225 65 17? Again only 0.10" diameter difference.
That's only 3 revs per mils difference, compared to closer to 17 revs
per mile difference between 225 65 16  and 225 65 17.

Verified it off the tires. That's why I was questioning what the
advantage, if any, to the 17" was. Same profile, just an inch taller.
The 2008 Dodge Grand Caravan SXT option packages M & N
came with the 17". For 2009, only the 16" is available.
P225/65R17      P225/65R16  
17 x 6.5 rim    16 x 6.5 rim

 Then the only difference is one gives you half an inch more ground
clearance and throws the speedo off one way or the other, depending
which tire the vehicle was delivered with/calibrated for.

16s are definitely cheaper, and if you want the extra hight you can
always put 70 series 16s on - likely still cheaper than the 17, and a
better ride to boot.
