69 Dart swinger tire size

I run 225/70/14 at all four corners of my '73 Swinger with 14" x 5.5"w rally wheels, FWIW.

It's a little spongy around corners, due to the sidewall flex, but I take my corners pretty fast too lol.

It's also a little wide for the wheel. I have some sidewall bulge, but it looks pretty good IMO.

215/60/14 or 215/70/14 may fit a little better and not bulge as much, but I wanted a taller tire for my combo.
