Wheel and Tire Help... 65 Barracuda

Fronts will be ok....Maybe a tiny bit of trimming on the front bottom portion of fender. No biggie

245 are starting to get very close on the rears. Backspacing will be key
Here is a pic of a 235/60-14 on the rear on a factory 14"x5.5" steel wheel.
To play it safe,I would go with a 235.
