Never take anything for granted, especially tire sizes. I just assumed that going from 205/75-15 to 225/75-15 would be fine with no issues. That first number, 205, 225, etc is the “Section Width” (cross section) in millimeters and that second number, 75 is the “height” of the sidewall, expressed as a percentage of the section width. If I have you lost with the technical stuff, do what I did and go enter some numbers at https://tiresize.com/comparison/ to compare tire sizes. Not to get off topic but I find it interesting that being able to comprehend something is just sometimes easier by visually seeing what you are trying to explain. Anyways, even though I visually saw that my new, suggested more expensive Goodyear trailer tires with fancy new wheels “that were just a little bit bigger” did not mean all will be kosher. In reality they did fit but unfortunately that 1.2 inch overall difference in height was a little to much. Any kind of bounce going down the road would have destroyed the tires because they would have hit the top of the wheel well housing. Even with the factory tires I noticed some slight rub marks in the wheel housing so I’m not sure if I should blame the tight tolerances or the poor engineering. With any issue there is a solution and this is one time to be thankful for the internet. A little bit searching showed me that all I needed to do was reverse placement of the axle, moving it from the top of the leaf spring to the bottom. Dexter does make a kit enabling you to do this but if you have the tools and the ambition you can do it for half the cost. I am going to let my photos do the talking on what you will need and the process. The end result has giving me more ground clearance and tire clearance although it places the trailer higher in the air with more ramp angle. In the end though a lesson has been learned, don’t assume something will fit… the details are in the pudding, and if not it’s in the measurement…
