Back in the 1980's I built a 16 foot utility trailer. I bought an axle then went to a salvage yard and bought four rims. I would like to carry a spare on the trailer. The center hole of the rim is 4 1/8 inches and center of bolt to center of the next bolt is 3 1/4 inches. The center hole is larger than a typical rim. If I remember right the rims might possibly be from an IH Scout or Travelall? Maybe some kind of Jeep? I really don't remember. I have attached a photo of the center hole and lug nut holes. I think some Ford rims might work but I haven't found one with a large enough center hole. I have taken a cutting torch and enlarged a rim so it would work once, but I think that probably weakens the rim. Thanks for your help.
