A good compromise between looks and efficiency could be to go with 20 wheels and 235 width tyres instead of standard 245. 235 is as far as I know the width of the standard 18 tyre.

I think the main difference would be the tyre width. To maintain the same rolling radius the 18" tyre is 235, whereas the 20" is 245 and 22" are 255.

I imagine this will have an impact on both aerodynamic drag and rolling resistance. The higher sidewall should mean a softer ride, but will suffer more with roll.

I am looking at 19" myself because the range of available tyres at reasonable prices is wider, but, unless I want to pay to get the speedo etc recalibrated I am still going to have to go 255 to retain the same circumference.

The Goodyear Eagle F1 Asymmetric 3 SUV 235/50r20 have rolling resistance "A" that is very rare for 20" tyres. Is it possible to have the car delievered with other dimensions than standard if you ask for it?

The wheel set comming with the car would probably need to be one of the standard configuration I guess.
