Stock 64 dart fitment

I ran these on all 4 corners and they don't rub. Very similar to your 15 WW's, only .2 shorter.
205/75R14 tires have a diameter of 26.1", a section width of 8.1", and a wheel diameter of 14". The circumference is 82.0" and they have 773 revolutions per mile.

Walmart still sells 14's in whitewall. I bought a set for my 82 Mazda B2000. They got a 205/75R15 in WW. https://www.walmart.com/ip/Uniroyal-Tiger-Paw-AWP-II-All-Season-Tire-P205-75R15-97S/9720481
