We're in the process of changing our new Kinze planter over to the RID tires. We are putting on CIH tires. Problem is the CIH tires are @ 1/4" wider than the original Kinze tire. We tried bushing them out, but think we will run out of the mounting shaft before we get where we want to be. Anyone else have this problem and how did you deal with it? Thanks for your help.
