I have an oliver 80 that isalmost completely restored. I need rear 40" rims tried 40" 70 ri ms but will not work, What do I need to be able to change to 38" rims and tires
 
Years ago another man had the same problem. They found a railroad lathe that would handle the 40 inch castings and turned them down to 38 inches.
 
Well,that was foolish wasn't it? You said 70 RIMS wouldn't fit it.
Guess I had my own 70 on my mind. Finally found a set of decent 40 inch tires for my rims on cast centers,but I have a pair of 40 inch 70 spokes here too. I'd thought about cutting them down and putting 38 inch rims on those,but I didn't have to resort to that.
 
This in the 1935 model 1827 that I am working on. It became the model 80, so the axles are the same. I used the center cones from an 80 and 40" cast centers from a model 70. The rims are also 40" 70, but I widened them to fit the 13-40 tires.

Use Oliver 70 cast centers for 36" tires, with your 80 tapered hub, and use IH M or JD G drop center rims. Done this two times before works great.
