But honestly, i thought it was pretty well known that the huge rims with tiny tires are completely moronic from the POV of fuel economy. Unless, you spend a lot of money on really light rims.
These look like they're more outer heavy than center heavy.
Yes they're crap from fuel economy perspectives but 29 or 31lbs is the spec I found for these wheels. That's a bit much even for 18s when most of the aftermarket ones are in the 22-25lb range.
