i'm in the market for a 16+ QX60 fully loaded.. and they all come with 20" wheels.
it looks nice, but i have a feeling that the ride is rough, and tire life is 20-25k at best.

thoughts?

I believe they are 55 series so there should be plenty of sidewall on the 20's to not drastically effect ride quality. I'll let someone else comment on mpg.

i had a loaner w/ 18s for about 6 days. it was a 2017, and i averaged about 20mpg. i get about the same on my 2016 w/ 20s.. so maybe there is no real mpg difference. i didnt notice a ride quality difference. (aside from the zippyness of the 2017 more HP)
there is definitely a price diff in tire price however :D
