People who care about only looks and not weight deserve to pay every dollar of the fuel economy they are throwing away.
I would greatly appreciate lightweight wheels that are still strong enough to not ding on every pothole.
I changed my 16" Honda Civic OEM wheels that weigh 25 pounds each for 18" Motegi SP10 wheels that weigh 19 pounds each, and even with Z rated tires I don't lose fuel economy because there is so much less rotating mass.
I have the OEM 17" OEM wheels, and if you could offer a wider 19" wheel that was significantly lighter than OEM wheels I would very much like to buy them, thank you.
Looks are obviously important but secondary.
