215 60 14 tire

215's on a 6" rim will fit all day long.
Ive run 235's on 5.5" steelies with no problems.

My suggestion to you would be to run 70 series tires on your 14" rims.
They fill the fender well up much better than 60 series.
215/70-14 for example work well on A bodies.

i was going to suggest this.
215/60 may look a little short compared to the 255/60/15's on the back
..it may look a little more balanced with 215/70 up front to some..
