Tire pressure

Hard to believe that after only 66 some years of service the rear rims had given out on the old H.

They originally run loaded all these years would explain why the extreme corrosion in the photo.

My question is: The manual states #16 psi max tire pressure un-loaded.

I thought that sounded almost too low ?
 
Common pressure in rear tractor tires is 10-15 PSI. Higher for less traction and heavy loads like on 3 point if you have one. lower for more traction and light loads on things like the 3 point. Less pressure means more tire on the surface of the ground
 
Well okay then .. this would make it official.

I backed off to 15 lbs and will run them awhile and see what I have.

I am about to hang the next one now .. and I won't need to mow that area for the rest of this year.

What a back breaker too.

Thank you guys
 
We generally ran 12 to 13# in our bigger tires like 12(13.6)x38, and 13 to 14 in smaller rear tires like 10x36. Can't remember ever running more than 14#. I have 12# in my 14.9x24 tires on the 240U.
Unless you are carrying a lot of weight on the rear, either mounted or in wheel weights, I'd drop them another 1 or 2# to 13 or 14. Better traction and better ride.
 
Doing tires are not all that bad if you have the right equipment to work on them and the knowledge to do it. Most of the time what makes them hard to do is either not know the correct way to do them or not having the equipment to do them. That said if you do not have the info on how to change them out send me an e-mail and I will send you a page from an owners manual that explains it
 
If you're plowing, have enough pressure to prevent buckling of the side-walls. have somebody walk alongside for a while to check.

Thank you Old .. but I did manage. I think the last time I did this was when I was in my teens. It was my grandpa that showed me a few tricks.

I have a heavy flat end pry bar and a couple of truck leaf springs to start walking it off (or on). I put the truck in four wheel and drive up on the tire to break the bead.

Crude .. but it works.

I killed a bunch of grass too draining them off *lol* I won't have to mow there.
 
OLD, your email address is not in your profile. I'd like to get a copy of that tire changing instruction sheet.

Thanks,

CT
