Type-S on 16" rims feel "faster"
I switched to my winter use rims last week. I picked a set of '03 Honda V6 Accord rims (TSX style 7-spoke) with 6,000 kms on the stock Michelin Energy rubber (205/60/16) and scored it for $500 bucks.
First time I had it out, the car felt different. The higher rubber felt evident when I hit bumps and curves and the ride was a bit softer and quiter. Sudden takeoffs also felt that it was missing a little bit of "grip" and the torque was more prononced on the steering wheel.
What I also noticed unusual is that car felt lighter to accelerate and seemed more "eager" to get to speed. It didn't seem that there were much weight difference between the stock 17s and the 16s when I was mounting them. (also found out that the stock TL-S rims are by Enkei).
Does this mean that the stock 17s create more drag? resistance?
What are your opinions?

I believe that a smaller diameter wheel actually helps acceleration. Laws of physics...
Update: I made the assumption that the overall diameter of wheel AND tire had been reduced...

First of all, it has nothing to do with diameter since the overall rolling diameter of the rubber will be virtually identical.
What it probably has to do with is the lower weight of the combined wheel/tire combination.

Smaller wheels give the effect of shorter (numerically higher) gearing.
Smaller rims do tend to allow the wheel/tire combo to spin up faster, because the weight of the wheel is located closer to the center. It's the flywheel effect- the more weight you have the further out from the center, the higher the inertial component (meaning the more it resists speeding up and slowing down). Most of the weight of the rim is in the outer ring portion, so you can see how "upsizing" a wheel will tend to slow down acceleration a bit. And, the weight of the wheel is the dominant effect, over and above the weight of a taller tire, due to the location of that weight.
These are things that drag racers have known for eons.

16"s are faster when accelerating in a striaght line than 17" because the 16" wheel/tire combo is lighter, but the car's cornering ability is greatly compromised because of the higher and softer sidewall and contact patch.

hahahaha wonder if someone will say yes. I don't think 16" makes that much a difference. But if i had rims to switch to in winter I would. I hate scrubbing when rain season over but i love my car so I'll get around to it neway.

What can be uglier than your beloved TL-S in snow and slush with your stock rims on sloshing thru all the muck. Then in summer, your clearcoat is all peeled to crap because of all the salt, brine and sand they used to melt the snow and ice.
Once you get cracks on the clearcoat, small parts of brine (salty water) seeps into the cracks and corrode the bare aluminum underneath. Once this happens, you need to have your clearcoat and the wheel refinished.
I would have even settled for snow tires on black steelies for the winters, but for the deal I got on those rims, the car still kept "some" nice looks.
