1965 Barracuda.......new wheels.

centre caps are painted black cherry with white centres

bigger tires on the back improved the stance (lifted 1.5" at the axle) and added 9" to the circumference (over the 13"ers that were on it)

increased gas mileage 12% - 2700 rpm @ 65 mph in 4th gear (sorry, don't know any of the gear ratios)
