yeah 17 will be way better for tires.. my tires make me cringe at the replacement cost..
adding 1kg to the wheel is like adding 2 anywhere else on the car because of rotating inertia. heavy wheels are awesome for fuel consumption on the freeways and open roads but kill on city driving.
width of the wheel that is driven does not make an impact on the consumption, but width of undriven wheels makes a difference.
all of these differences are not that great however like u said

here is some food for thought. my wheels were gold when i got them. but for around 400 u can powdercoat them whatever colour u want. so get some that u love and change the colour.
also ARI i think is selling his white 18s (exactly same as myn)

here i even looked for the link
