Is it me?
Every year when I take off my 18 inch summers whether they are 225/45/18
or 245/45/18 and put on my stock 17 inch mags with my winter set up 215/55/17, the car always feels quicker and lighter. I drive a 03 sedan..
What gives, is my butt wrong...........maybe I will try 235/45/18 next year..

Because whatever your summer wheels are tires are, they are probably many lbs heavier than your stock 17s.
I noticed this too when I ran my coupe 19s on the rock heavy RE050s. When I swapped them to my pilot sports, there was no difference in acceleration when I swapped. I researched and my fronts are lighter than stock and my rears are only about 1-2 lbs heavier than stock.
I always thought drag racers ran small wheels so they can run a tire with the biggest sidewall (for traction)

EVen if the weight of the wheels is the same, you are moving the largest peice of mass (the wheel rim) further away from the center of rotation. The further away, the more energy it takes to accelerate and brake the wheel.
That's why drag racers run as small a rim as they possibly can and why guys who add huge wheels to their cars usually find their car doesn't brake as well.

I forgot who said this on here but True enthusiasts and racers put the smallest rim possible to cut down weight.

^^ If you're running OEM RE050 Bridgestone tires on those 19's you'll notice they are quite a bit heavier. You can save at least a couple pounds per wheel by going with a lighter tire. My next setup will have lighter tires.

I'll gladly trade the slight increase in acceleration (probably .15 seconds and 1.5mph in the 1/4 mile) for the stellar braking, handling, overall feel, and style of my 18s and summer rubber.
