I over inflated a tire that is filled with Rim Guard in it.

[All In A Days Work]

I had not checked the tire pressure in my tires for couple years, it's not used all that much. I noticed they were bulging some the other day and decided to check the pressure, neither rear tire would indicate air pressure. I checked the gauge on front tire it works. I started airing up the tires, I could hear that the valve stem was below the fluid level. I checked 5 lbs. ok good, here is where things went bad. I just wasn't thinking clearly, the next thing I know I had 35 psi in one of the tires. I tried to let some out but after I lost some Rim Guard, I decided I needed to come up with another plan. The tires are the 17.5 x 24" Ag tires, the manual states that they would have about 600 lbs. of Rim Guard in each tire.

The dealer told me it would be best to lay the tire down to adjust the air. So here is the plan, in my pole barn there is a center beam that I thought I would hang a pulley from and then with my portable winch I could hold the tire while unbolting and then lay it down to let some air out.

How does that sound?

If properly filled, the rimguard should be below the valve stem when the valve stem is at the top of the tires rotation. You should be able to release the over pressure without loosing the rimguard.

 

[Wolverinefarm22]

Yeah, drive ahead until the valve stem is at the top and it should be good to let out some air

That's what I thought, but nope I had the valve stem at the top and the rear of the tractor was jacked up. The dealer told me that at 75% fill it was above the stem. My manual shows it below the stem. So, in my mind the tires are over filled with rim guard.

 

[Wolverinefarm22]

Definitely sounds over filled

Do you think I should jack the back of the tractor up put the stem at the top and remove the core and just drain the rim guard out? I could probably arrange some sort of collecting device/pan so it doesn't make such a mess.

It's been more than five years since I've checked the pressure in the rear tires. Roll the tractor forward until the valve stem is at 12-O-clock high. Shoot a blast of air into the stem to clear any Rim Guard. Take your reading.

Every spring I move the tractor out onto the driveway. Drive over a dirt section. Check the bulge and check that I get a full chevron pattern all the way across the tire track mark. The bulge and chevron pattern are both OK - all is OK.

Last time I used a gauge to check - 15 or 16 psi.

All in a Days Work - if you are getting Rim Guard when the stem is at 12-o-clock - the tire is way over filled. Now - be sure this Rim Guard you are seeing is not just what became stuck in the valve stem. I would guess a normal stem would hold a couple tablespoons at max.

75% puts the level just below the valve stem. At least, in my 16.9x28 R-1 rear tires.

I would probably drive it for a few hundred feet if ya hadn’t already and stop with the stem at the top. Just let air out til it’s at 16 or so. I can’t imagine a ton of rimguard would come out but could be wrong. Either way it’s just beet juice so no harm in a small amount of spillage to get your tire right.

I've used barn beams for lifting before. Work as close to the wall/posts as possible. Preferably if you have some diagonal supports.

You'll probably minimize the height of the fluid above the valve if you lay the tire over with the valve side up on a 2x4 or 4x4 so the valve exiting the rim will be slightly above the rim on the opposite side.

So - You think the tire is overfilled with Rim guard?
Well just put the valve at the level you want the fluid to be and start draining it.

 

[dodge man]

I think I’d just let the air out and figure sone rimguard is coming out also.

Can ya throw down a couple blocks of wood and drive over them with the rear tire to angle it a bit. That could drop the fluid level at the valve stem a couple inches. Obviously don’t flip your tractor.

I tilt my truck to intentionally overfill my manual transmission a tad, in order to ensure the input bearing doesn’t get oil starved. It’s a similar concept.

The dealer prep on my little Kioti CK2620 included filling the rear tires with rim guard.
I realize that for most dealers tire and tractor prep after a purchase is going to get pushed to the cheapest employee.
My front tires were inflated to 25 psi with a sidewall max of 45 psi.
The rear tires with a sidewall maximum pressure of 35 psi were inflated to over 45 psi ( my filled tractor tire gauge only goes to 45psi ).
Complete and total screwup.
I drained several gallons of beet juice out of each rear tire untill I got them down to 20 psi, looking at the tire foot print even with the backhoe on the little thing they are still a bit over inflated and then I broght the fronts up to 35 psi to handle the loads it gets with the loader filled.
I just pulled the cores out of the tires with the valve stem at 12 oclock, and let the juice flow out on the ground, I had the water hose running to keep it moving away.

Good Idea, I live on hill property that will be easy to try.

One thing I did with my tractor was to adjust all four wheels as wide as possible because of the hill.

Worth checking if you are planning to remove wheels anyway.

 

[Skeletor]

I would just put the stem at 12 and pull the core. If it’s overfilled get it to where it needs to be. I’m not dicking around with a 700 pound tire unless I really have to.

 

[garry1p]

I agree if anything goes wrong R&R a 700lb tire that would be a major event.

 

[LouNY]

Put a jack under it or if you have the backhoe on it the outriggers down.
If you don't it will push out fluid till the tire is mashed down flat on the bottom which is a bit more then you need to remove.

Don't take the wheel off. It is just plain too dangerous. I can see that center beam in your pole building breaking, and then you getting hurt by the falling wheel and beam. About twenty years ago my neighbor and I removed a rear wheel and tire filled with calcium chloride solution from a Ford 9N. Even with two of us it was scary and dicey. That thing kept trying to fall over as we rolled it to the wall only a few feet away. We both realized how stupid it was to do what we did. We ended up using my backhoe to put the wheel back on. That was so much safer, with the wheel chained to the dipper and both of us well away from the thing.

I have a couple of jack posts, that I can put in place just for this type of thing. I'm not concerned with the beam breaking. And with the winch setup like a hoist, I'm not concerned with the weight very much...... That being said, the consensus is that the tires are over filled with Rim Guard. So, I like the idea of jacking the back of the tractor up and pulling the valve stem and letting it drain until I get air. I'll probably try and collect as much as I can, just so it doesn't make a mess in front of my shop. I'll have to see how that goes as it may not be as easy as I think to collect it. If I collect any I will use it for dust control further up the hill.

Thanks for all the advice, ideas and concerns, I really appreciate it. I probably won't get to it until this weekend or maybe next week. I will post a follow up on how it went.
