Height Impact of Loading Tires

[Red Horse]

Anyone have an idea on effect ballasting tires has on total height? I have 17.5L-24's on my JD 4720 and just replaced my barn doors with an OH- (didn't want to spend a half hour shoveling snow before I could get the Deere out-wasn't a problem this winter:laughing.
In any case with the new door open, I have 1/2" clearance under door. My guess is when I load the tires, I should get a bit of sidewall defelection and if anything should pick up a bit of clearance.

Any opinions?

Not sure you would lose or gain anything height wise by loading the tires.

Chances are slim, but you may. You still need to inflate the tire to the recommended pressure with air, or just put enough air in so all the tread is touching the floor. I did the latter.......I have no clue as to how much air is in my tires.

My tractor tires is so small, when I added liquid ballast, there seems to be no height difference.

Its not gonna make any difference.

I see your concern about having only 1/2" clearance under the door. You first could just fill them with water and check the clearance to be sure, then drain and fill with your choice of solution. There will always be some water left in the tire-that area below the valve stem when at 6:00 unless you break down the rim or use a real skinny straw.
I wish this was posted a few days ago when I reloaded all four of my tires and I would have done the measurements for you. Perhaps someone else is getting ready to do it.
Any chance of a modification to the door frame? Change out the 2x bottom trim to 1x? Is there any 2x fill stuffed in the wall under the existing header?
Oddly enough my recently filled R1s look as if there is more casing touching the concrete than when only filled with air so MAYBE the tractor dropped a fraction in height.
The reason that I drained and refilled was due to installing some additional rear hydraulics which required a rear tire removal that was safer to do empty. I discovered that the solution was just plain water so I drained all three-yes, all three as the shop where I bought the tractor new several years prior missed filling one of the fronts! Lunch break??? The sales person never even told me at the time of purchase that the tires were filled with water. They're now bathing in RV antifreeze.

I would be really surprised if it makes any difference, and if it somehow did it would be very minor and would lower it, so if it fits unloaded you would be fine. One trick you can use is to adjust the oh door so it raises inside of the entrance frame if its the entry that is the issue vs the interior.

just using liquid balast or wheel weights you don't gain or loose anything on hight with a properly inflated tire. There is a minimal hight gain/loss if you have 8psi or 15psi of air in the rear tire.

 

[SSdoxie]

There is no change of height with fluid in tires. Only change is amount of air required to bring tire up to correct inflation.

I don't know about liquid ballast but I can tell you that I had all tires on my Kubota B26 filled with foam last fall and I had to remove the 3/4" trim above my garage door in order to get it through the doorway.

You might be able to adjust the travel of your door to get a bit more height. I had to do this with my garage door when I had a fixed ROPS 790.
If it's the door's frame that's a problem...well, not much you can do about that without some work or money.

As far as your question, my tractors have had filled tires when I bought them, so I can't answer your specific question.

One thing you can do is, when you're expecting a snow fall, is back the tractor in your building. If you use your loader for snow removal, you can clear the snow as you move out of the building rather then ride over it with your rear tires (which probably wouldn't work with that 1/2" clearance).

Inflation pressure and axle loads determine the tire's loaded radius. Liquid ballast won't change either variable, but your inflation pressure must be set the same after adding liquid ballast as it was before. Foam-filling tires alters the tire's contact patch and loaded radius.

I installed a garage door opener to keep my door fully raised in order to confidently clear the ROPS.

And that is what the next step is! Actually to give me the 1/2" I have now I have a block of wood jammed between the door jam and the bottom of the door-that pushes the door to past the point where the cable/roller would normally hold it.

Just so you all know, I didn't have much choice here. this door is on a shed side of my barn and an 8' height was the max I could do-I guess without spending a lot more on a custom door. the attached shots shows the new header I cut in-as well as the temp extensions I added to the old barn doors while waiting for thje new door.

Thx guys for all your opinions- I think the consensus is I will be no worse with the tires in ballast.

I have the same tires size tires on my L5740. I had mine loaded with RimGuard. 55 gal per tire with a total weight of 1298 lbs. I only run about 10 psi in my rears otherwise it's a little rough without an implement on the 3 point. I the tractor definitely didn't grow any. If anything, like you said, I think it squats a little.
