I bought a versatile tractor a couple of years ago, It has six firestone 20.8 R 38 champion spade grips on it, tread pretty good.  The ouside duals on the rear are goodyear, and not holding up so well.  Sidewall just gave out on one.
     I have called the salvage outfits down in the MO. bootheel, they and the tire stores they recomended couldn't find any.  Radials in this size hard to find apparently.
If anyone can think of a place that might have these tires used, I would sure appeciate the help.
