19” vs 20” vs 21” wheels

[Pulone]

I know RWD comes with 19”, Advance 20” & the Performance 21” wheels.
I think 19” better mileage vs 20” & 20” better mileage than 21” wheels.
there must be an advantage of the larger diameter wheels vs smaller diameter wheels. Obvious guess is handling better with bigger wheels.
anything wrong with my logic?

Its purely aesthetics!

Yup, although I don't necessarily buy into it.
I went down from 20" to 19" with a greater aspect ratio (and better tire than the OE) and got a quieter, smoother ride with better mileage and handling.

What kind of rim and tires did you choose?

Pirelli AS Plus 3 - 235/55 R19 105V
Love 'em. Much more smooth and quiet than the OE Michelin's. I also have gained some mileage.

I'm curious Artie. Do you ever drive on Highway 85. I find with the OEM Michelin tires on that freeway only, the tires jiggle back and forth on the rain grooves. Did you notice that with the Michelins? If so, does it also happen with the Pirellis? FYI we have the Advanced Model with the 20" wheels.

Not 85, but there is a section of 580 near me that would do that with the Michelins and it drove (pun intended) me crazy. Rear end wobble / shimmy / vibration that I knew (hoped) were the tires, but thought maybe un-balanced. I had them balanced, but it did nothing.
An Oakland pothole ripped open the two right-side Michelins, and I rode on the rims for 2 blocks to a tire shop that put on some Arroyo's (happy they had something in my size), but that was what inspired me to replace all 4 and get smaller wheels.
Wobble is 90% gone with the Pirelli's. They are just amazing. They were all I would put on my Audi's and I loved them.

Yeah I know it is the tires and the rain grooves. Only happens on 85 and I had the same issue with my Harley.
