Agreed, 225/70R14 - or in a 75 or even 78 section would look more accurate.
The older sizes were more like a 78.
Depending on height/width/wheel offset, check clearance at the front bottom corners of the fenders.
I've run 215/75s front, and 255/70 and 285/70 rears on 15s on early Bs; the 285s were a tight fit even with narrower rear axle.
