Tesla Aero wheel vs lightweight Forged wheels

^ That, except maybe for aesthetics.

Narrower tires also helped.

11lb HX wheels plus 185 width tires added 2-3 mpg over stock 15lb wheels plus 195 width tires on Silver Aero, depending on route.

You may need to develop a context for "light weight wheels".
For example, the lightest 13 inch wheels I could find for my trailer were insite wheels at 12 or 12.5 pounds each.
Went to tractor supply and tossed one of their steel trailer wheels on the scales, 13.5lb.
So there was no way it would ever be worth $50 to $100 more per wheel to save less than 2lb.

Consider taping up your existing wheels and road test for data which will demonstrate,or not,enough savings to justify the investment.
If you don't see a benefit from a simulated flat disc wheel,you'll never see a benefit from the TESLA wheels.
