Toyota will see you guys are still pulling of your wheel covers, next year go to the "raw casting" look, no paint, pebble finish from the sand casting, rough edges.
But I might think raw castings are lovely. They could've saved themselves the trouble and maybe some expense by either: a. Hiding black steel wheels under those supposedly aerodynamic wheel covers, or b. Using reasonably attractive and aerodynamic aluminum wheels without wheel covers.
My guess is that due to some aerodynamic phenomenon, the wheel/wheel cover combination is what results in the increased mpg, otherwise they'd just make a wheel that does the same thing. I wish I could like the black wheels with black tires against the Blizzard Pearl white, but I don't. So, the covers stay on until I need new tires and get new wheels, if I decide not to trade for a newer model.
Anyone priced those wheel covers, at a Toyota dealership parts dept? I'll wager they rival aftermarket alloys for price. Guess it's a case of "if you have to ask...".
I was thinking there was a financial reason to do it, just in case someone needs a replacement. I think they're around $60 or something crazy
