Yeah, 225/70R14s are few and far between. Firestone makes the Destination At and LE in that size. Toyo makes the Open Country A/T in that size too. Cooper makes the Discoverer ATR in that size but isn't all that great when the tread is half worn down on wet roads. Cooper also makes a winter tire in that size, Discoverer M+S. They are the only one that makes a winter tire still.

If you are inclined, get some junk yard 15" rims for the Ranger and you'll get more options.
