Chris the tires could have come from Good Year, Firestone or BFG. And the rears would have been either 23x8.50-12s or 6.00-12s in either ags or lawn treads. The fronts would have been either 4.00/4.80-8s or 16x6.50-8s in a lawn tread. To confuse things even more it was not unusual to see new tractors with Firestones on one end and either BFG or Goodyears on the other end. Roger
