Farmall H width

Hello all again. I have a 1944 farmall H with 13.6x38 tires on it
and it is realy tight loading it on my trailer. Both sides rub. I
have the centers pushed all the way in, still dished out. I
would like to keep the centers dished out if possible. I want to
trailer it to my wood lot and the lot has a slight downward
grade so I want them set wide as possible. I am hoping
someone here can tell me what the overall width of an H would
be with 12.4x38 tires on it to see if I buy a set of them if it will
fit on my trailer. My trailer is 6'-3" wide and has side rails so I
can't overhang the edges. Thank you in advance.
 
I'm wondering why you wouldn't turn the wheels around (to dished in) then slide them out on the axles to match the width of your trailer? Wouldn't your H still be as stable dished in, as dished out, at the same tread width?
 
I agree. Save your money and use what you have. Dish your hubs in, and adjust treadwidth as wide as you can, but just narrow enough to fit on your trailer. If you can fit on your trailer now, you really only need to narrow it up another 2" so your not rubbing the rails.
 
Dish in makes the load on the axles way greater for more chance of breaking. I would never dish a wheel in because of that. They were shipped like that to get more on a load and dealer was supposed to dish them out before sale but a lot of dealers were too lazy to do that so people thought it was OK to use them like that. Had a 41 H weels dished out and after 30 years think wheel tread was 66" slid in and dished out on 12.4 x 38" tires so should have been 68-70" to outside of tire.
 
Shouldn't matter if the dish is in or out. Stress is only determined by where the tread contacts the ground, however far from center that may be.
 
Your statement is very correct. The maximum load on the axle shaft occurs right at the bearing and for a given tread width this load is the same regardless of how the wheel is dished. The manual for my 350 lists the tread widths available for both configurations so either way is "factory approved".
 
I've seen the wheels turned both ways in IHC advertising literature of the time, so either is correct. That said, I don't remember seeing an H with the wheels turned "in" when they were in common use. I think an H or M just looks better with the dish out, but that's me. You can gain just a bit by putting the removable clamp on the inside of the wheel. My 1942 H with 12.4x38 tires has about 1" of clearance on the inside of the rails of my trailer(75"). Makes for careful loading, but it's doable. If it had 13.6's, I don't think I could load it.
 
The Farmall M tractors that we had in the 1940 and 1950s always had the wheels dished in. The shear on the axle is the same whatever the tread width (fore the same tractor weight) and the maximum bending moment on the axles depends on the tread, maximum moment at maximum tread. In fact, I have seen very few Farmalls with the wheels dished out.
 
A 12.4 tire is about 1.2 inches narrower than a 13.6. You would gain half of this measurement on each side so the overall difference would be just a bit over an inch. Differences in tire manufacturer will also vary a bit.
 
All my Farmalls(from H to 1256) are dished 'in'.they have to be that way in order to get them to 60" center to center.That way we can fit down a 30" cornrow.There was no 'factory correct' way. they were made to set either way for more versatility.Dish em in.Then set em as wide as the trailer permits.
 
Thank you to those who answered with the widths. I may be able to get a decent used set of 12.4s very reasonable and it sounds like they may work for me.

My trailer is what it is and I cannot afford to replace it, so that option is out.
 
The force of the load is actually centered on the tread of the tire, not on where the wheel is fastened to the axle.

Dish in or dish out the same load is being placed on the bearings if the tire is set to the same width.

But excuuuuuuuuse me for not answering the exact question exactly as it was asked. Sorry for bringing up ideas for alternative solutions that you might not have thought of, that don't involve spending lots of money (which you indicate you don't have), or performing lots of bull work (even flipping the wheels to dish in is less work than beating two stiff old tractor tires off the rims).
 
You wont gain (or loose) enough to be worth to bother with. Wheel swapping is easier(and lots cheaper) than buying tires.
 
Leroy,you are mistaken.Tractors were set up for the most common conditions/requirements of an area. In the midwest,Farmalls were dished out to accomodate a 38" corn row.In areas where narrower rows are used,they must be dished in to be narrow enough to fit.The load is centered on the center of tire.In fact,the only time I've ever encountered a broken axle was on a 300 with wheel disked out.
 
One problem with dished in is that the clamp is at the edge of the axel. If you let the bolts get lose you will find youself sitting on a slant. Experienced it twice. Now I have one dished in an one dished out on one of my H's.
 
6'3" trailer with rails,
doesn't look like you have much of a choice.
Turn them in.
doubt 12.4's would make a difference, tire squat would still get you.
With the price of tires, no way would I risk cutting a tire.
If your tires aren't loaded, once you have them loosened and off once and clean all the rust out, changing widths only takes a few minutes.

Amazing how narrow you can get those H's. Bought a few from a guy that used to maintain sidewalks in a town with them.
Tires would about rub your elbows.
