65 Cuda wheels..which way to go?

I didn't investigate 15 inch wheels because of a preference for color coordinated painted stock normal size wheels with small caps. It's a look that gets many thumbs up.

Even though 14 x 4.5 wheels with 185 x 75 radial tires don't work with the standard scarebird kit I modified the kit to make those wheels & tires work.....gas mileage efforts include tall, narrow tires with high pressures..... 65 dart sees 26 mpg for winter, all around, hilly country driving.
