Front and Rear Tire Pressures

Dave Miller · Apr 22, 2012

I have Farmall models A through M. I have been looking for the tire pressures for the fronts and rears of all my tractors. I have had so many inputs from different people, I would like a place to go and find what I am looking for. Thanks for your help.

I put air in mine till they look right, basically till the sidewalls are not excessively bulgy. Then when they get soft I put in some more.
Probably there is a better way, but this seems to work pretty well for me.

Check out this site for a Farmall H. Your other tractors may take different pressures, but this is a start:

Have you looked in your Owner's or Operator's Manual? I looked in mine for the Farmall tractors I own (several different models) and all the front and rear tire pressures where shown in a table. Go to the back of the manual to the index and look under "tire pressure, chart" for the page where the info is shown. Various factors affecting correct pressure include the tire size, number of plies, what tractor is being used for, etc. Pressures are different for various models. The tires usually also have the maximum pressure molded in the sidewall as well. Hope this helps but the correct information is readily available, Hal.

From the Farmall M Owner's Manual, Page 32:
All 4-ply front tires.....30 lb.
All 6-ply front tires.....36 lb.
All rear tires..............30 lb.

I don't have my Farmall H manual at home just now, so can't help with that today.

Here in the US the rears take around 13, but nowhere close to 30.

look in the manual for the safe pressure range,
then adjust for what you use it for.
heavy load, loaders, bale spears, rear forks, go high side
working dirt, adjust for maximum tire footprint contact
mowing, just putting around, go on the low side for a better ride

Now that is a very good point about high pressure for the rear tyres. I was not paying sufficient attention to the numbers when I looked in the book. The odd thing is, I got those numbers from a U.S. Farmall M Owners Manual.

By comparison, the Farmall AM Owner's Manual says:
For Front Tyre 6.00-16 at 6 ply 36 lbs maximum.
For Rear Tyre 13.5-32 at 6 ply 20 lbs maximum.
For Rear Tyre 11.0-38 at 6 ply 20 lbs maximum.

The Farmall Super AM Owner's Manual says:
Front 6.00-16 at 6 ply 36 lbs maximum.
Rear 12.0-38 at 6 play 12 lbs minimum & 20 lbs maximum.

I use a "rule of thumb" of a pound per inch of rear tire width plus two pounds. If you have a 12.4 X 38 or 36 inch rear tire, I would put about 14 or 15 pounds of pressure in it, depending on how the sidewalls look. If you have a 11.2 X 38 or 36, I would use about 13 or 14 PSI. Same for 24 inch rims. (My $0.02 worth. jal-SD)

jal-SD has a good rule of thumb for the rear tires. For example, the SC came out with 10X36 tires. IH recommended a minimum of 12 psig (10+2) for 4 and 6 ply tires. When plowing the tire on the furrow wheel was to be increased by 4psig.
The front tires, 4 ply were to have 28psig. For 6ply the pressure was to be 36psig.
