Denny,
215/85R16
It about 31.5" diameter rolling diameter and it looks narrow enough to appear to be original. They are spec's for 5.5"-7.5" inch rim - that is why they are wider diameter and look narrower on the 4.5" wheels.
Mine are Cooper SRM II LT (no longer listed by Cooper).
LT215R85 16" Cooper SRM II radials
They are 10 years old. My Goodyear dealer has 2 or 3 lines of tires in that size. I can look them up - I do not recall if they are LT.
