225/60-14 BFG Radial TA on 14x5.5 steelie
I ran them on the back of my '70 Duster for a while with stock 14x5.5" wheels and noticed uneven tire wear in the center after 6000 miles or so. I'd also recommend sticking with 215 or 205-width tires on those wheels. I had 205/70-R14 BFG Radial T/As in the front and they worked fine, wore much more evenly.
