Jubilee front tire pressure

[krogers]

I checked tire pressures on my, new to me, Jubilee. I found the front tires have over 60 lbs pressure in them. The tires are labeled as 6.50-16 6 ply. The manual I have does not show that size tire in the recommended pressures chart. The closest the chart comes to my tires is 6.00-16 6ply. The chart recommends pressures from 20lbs to 44lbs depending on the load per wheel. My thought was to lower the pressure to 40lbs to be under the max recommendation. Does this sound right? Thanks for any input.

If you do not have a loader on this tractor, 35psi will be plenty. 45psi would be my max if you have a loader.

Chances are that your NAA had a loader on it in the past. Without power steering, you put a wider tire and pump it up to make it a little easier to steer with a full bucket. I would not run more than 28psi in them and 14psi in the rears if you don't intend to put a loader on it.

The sidewall of the tire usually gives the maximum load the tire can support and the maximum pressure which would be used to carry that load. It is not recommended that you exceed the maximum pressure. You may wish to run at or near the maximum to make steering a bit easier.

Thank all of you for the input. I should have mentioned there is a loader.

Looks like a Wagner WM-4 loader.

I have 6 ply - R1 - Titans on the front of my Kubota M6040. Sidewall recommends 30 psi max. I have a loader and that is the pressure I run in the front tires.

Do you have power steering on your Kubota?

Whatever the sidewall states as max PSI is what you should use since it has a loader. No matter what since it is a NAA with a loader steering by armstrong is going to be fully present and felt.

If you're putting 60psi in those tires don't be surprised to hear an earth shattering Kaboom some day.
30-35 should be more than sufficient.
At 60 you're not only over manufacturers recommended inflation but also more likely to get a puncture.
Most yards I know have something even if it's only a pointy stone.

EdGooding - yes, I do have power steering on my M6040 Kubota. On my previous tractor - 1982 Ford 1700 - NO. It could be a real PITA with a bucket full of gravel on the 1700.

The 1700 was a great little tractor for the 27 years I had it. But fighting the steering was a real bummer. Almost 100% of my tractor use - whether the 1700 or the 6040 - was with something in the bucket on the 1700 or gripped with the grapple on the 6040.

I can't imagine grabbing a 3000# rock with the grapple on the 6040 and turning the steering wheel w/out power steering.

I've had the 2009 M6040 for fourteen years. Always run 30psi in the front tires. Never once have I ever rolled a front tire off the rim. Even with the very heaviest load gripped in the grapple. Whether rock or green tree trunk - when the load is 2500# or more - I go into the "knuckle dragging" mode. I leave the load so low - I will leave knuckle drag marks in the dirt.

Yeah, I'm spoiled. I can't imagine an FEL tractor without power steering.

And in regards to carrying heavy loads, if you don't have one back tire off the ground you aren't at capacity yet.
