Street Gear Poll
D70-14 on 340 cars,or E70-14 on 383s. The Es and Ds went on 5.5"rims.The rest got 6.95s, on 4.5s.
I have no conversion chart
Es are pretty skinny. I seem to remember Gs being 8.25, so an F might be 7.75, and an E, around 7.35. The 70 is a section ratio. So if an E70-14 was 7.35, then the section of 70% makes the sidewalls 5.145, for a final tire height of 24.3". That's my best guess.
