What Was the Standard Wheel Diameter for '65 Signet Convertible?

My non-Formula-S 65 Barracuda with Commando 273, four speed, ten inch drum brakes and handling package originally was equipped with 13 inch wheels.

Formula S Barracudas had 14 x 5.5 inch wheels standard.
My 65 Barracuda, (non-Formula S) 273 Commando, 4 speed, 7.25 rear, I bought from the dealer, came factory equipped with 14" wheels.
