Super H versus Super M Width

In Eastern Canada H's and M's were sold with what I call the drop center rim, or the old style. Every tractor from Super H, SuperM, Super MTA, 300, 400, 350, 450, 460, 560, 656, 504, 544, 666 and 686 all used what I call the double bead wheel, in that there were 4 position settings between rim and wheel. Some rims were wider than others and of course there was two axle sizes for wheels.

Remember also I am looking at this from a Canadian perspective. I can give you numerous examples of IH tractors and equipment using the same model numbers and were equiped much different in Canada from the US counterpart. I bought some parts books and manuals out of Nebraska. These were books I already had Canadian copies of the same. I did this because I saw discussion take place on forums, with participants trying to compare something that was somewhat different. An example, No.8 Little Genius plows. US built were non adjustable frames as to width of cut, while the Canadian built plows were adjustable width, narrow being 10, 11, 12 and 14 inch and wide being 14 or 16. There are 3 other major differences in those plows,yet they are both called No.8 Little Genius.

Another item and I just noticed Charles N on this one. He and I have had discussion on this one before, that being width of 38" tires. We saw wide 38" tires before you people did as they were coming out of Euorpe. We farm a much less firm soil than you people do, thus we were looking for flotation even for the H and M. I do know some US built Farmall tractors were shipped into Canada less wheels and tires, I don't know which models they were. We may have been getting wheels and rims out of Doncaster, who knows.

On your 13.6 tire, most of those tires will have stamped right in rubber on the side wall 13.6 on 12" rim, 12.4 on 11" rim or 11.2 on 10" rim, etc. That statment on side wall of tire gives the proper rim size for that tire, and indeed what will give you the very best traction all other things being equal.
