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

Keith Mopar said
My factory book shows all 1965 Valiant tires are 6.50 x 13 inches except Barracuda Formula S 6.95 x 14 .

Unless you had the factory tow package.

Factory tow packages came with
HD cooling
Front Sway Bar
10” Brakes
14” wheels
Wiring to accept trailer pigtail
