Hello guys, yay! I bought brand new front tires for my 1945 M, with the #33 trip loader. I do not anticipate doing anything heaver with the loader, just some ornamental rocks for the yard, etc. What PSI do I use?
 
Casemans 40 is good. More (maybe 45) is OK. high pressures sink in mud faster than modest pressures. Low pressures float better, but steer harder, Jim
 
Most tires have a PSI number right on them and that is a good place to start. Look the tire over and see what they say. If there is any warranty on them going over that rating can void the warranty
 

I have a #31 on an H. Same size tires. The loader and bucket alone will make the front tires squat if there is anything less than 45 psi.
 
After a lot of loader use years ago, many M and H Farmalls (narrow front)will have shaking front wheels when wide open in 5th gear on a road. Some JD will do that, also.

You can spend a fortune on the front steering gear and some shaking can come back. Tried that, it happened.

Best remedy: Put about 40 psi in right front tire and 15 psi in left tire. it will pull to the right a little going down the road but the shaking stops. Tried that, works and a cheap cure.

The wear factor is not much compared to the aggravation. After a few years if you see wear on the right, switch them around.

(quoted from post at 18:28:34 08/07/16) You didn't state a ply, I would try 40 and see how they hold up to a load.

Yes, recommended front tractor tire pressures are usually based on the ply ratings. A loader tractor should have at least 4 ply rated tires, a 6 ply rating is better. 4 ply tires are recommended for 28psi and 6 ply tires are rated for 36psi.
