I have a 800 Ford loader with The smaller set of pie weights and 16.9x24 tires loaded with water to the stem at top of wheel. I am going to install the factory rear weight box full of concrete on the factory backhoe mounts. Does anyone know what tire pressure I need for that amount of weight? I have no idea what the weight box weighs. Tires are 8 ply rated. Is it better to have them stand up some as opposed to looking like they are sqautting. Could I have too much water in them for the load?

One more thought!

It ain't "rocket science"!

You're looking for a "happy medium".

Just get it where the "squat" is right for the normal loading!

As Showcrop says, you will never know the exact loading, and it will be constantly changing anyway!

In other words, if it looks half flat, add air!

If it looks like the outer end of the bottom lugs are an inch off the ground, let some air out!

And another thought.
Add in dynamic loads, like a plow on the back of a tractor.
Plow on ground, you want lugs off the ground.
Plow in the air, lugs about level.
Pulling plow normal, lugs are buried, you look at sidewall flex.
Hard pull plowing, you have to air up or you will ruin the tires from flexing too much (like Fordfarmer said)!

OK JMOR, to start with Fordfarmer and Shetland sheep dog, and Adam at GCR tire in Manchester NH. I will try to keep thinking about this as there have been many many over the years. I will write them down as I think of them and post back. You see JMOR, PSI for given weight is only a good starting point. Given that one can never really know what the total of different types of ballast and mounted tools may be, the most effective means is to go with a performance based evaluation which is what it takes to get the tire to the desired footprint, which will be determined by the amount of "squat". I hope that this helps you to understand.

Maybe for all of us, you should copy one or two or more if you like that references "squat".

I have ALWAYS seen tire pressure connected to squat. It takes "squat" to being the outer end of the lug down onto the ground as Shetland Sheepdog says you want.

Fordfarmer nailed it!

Forget the tire gauge!

Park tractor on smooth hard flat surface, and inflate or deflate until outer end of bottom lug just touches surface.

Thanks for the replies, I'll see how they look after I put that box on the back.

I looked in my 26/36/41/4600 owner's manual. It doesn't say anything about different pressure for dry vs. loaded tires, only more pressure for more weight capacity. It listed 12psi as the minimum pressure for 16.9x24's, and 22psi as the maximum. I don't remember the exact numbers, but 12 psi was good for about 3000 pounds, and 18 psi gave about 4200 pounds of capacity. (Including liquid balast)

I've never heard of there being too much fluid (water) for a given load. You're still putting air in it to get to whatever psi you decide to run, just that the air is a smaller volume. My 4600 ( my loader tractor) has 16.9x30's with fluid. When I'm moving round bales, there's normally one on the 3-point forks as well as the loader. I run 18 psi in them.
You want the full face of the tread to touch the ground to get traction, but bias tires don't last if the sidewalls have to flex all the time.

Tire shop manager told me that a rule of thumb for bias rear tractor tires was take the first two digits of the tire size(16, in this case) and add two. 18 psi in 16.9 bias tires will work well in most situations.

14-16 PSIG sounds about right considering all of the added weight.

I have never seen a tire pressure connected to "squat".

I would think 12 to 14 pounds would be enough?
