Draining tire fluid?

[stlbill]

Hello,

My 10 year old tractor tires came with rim guard. The other day I noticed one is low. Trying to unscrew the tire valve resulted in a broken valve core and a fluid mess. It seems the sticky rim guard has stuck the tire valve. I sheered it off trying to unstick it. My dealer wants nothing to do with rim guard these days nor does one local tire chain I consulted so far.

I underwent the messy process of draining another tire (I have 2 complete sets all loaded), but cannot figure how to get the inside of the tire clean enough for a tire shop to change the valve core.

Short of using a sawzall to cut the tire off, to save the wheel and buy another tire... ideas?

I would like to replace with tire foam for weight.

I have no experience with this, but if you would otherwise pop the valve off to drain it, could you now just drill a hole where the broken valve is?

I'm not sure I'm understanding this. You have a tire that is filled with beet juice? You cannot get the valve core out because this sugary substance has "welded" it to the rim so to speak so the valve has been "cut off". Can you drill another hole in the rim acting as a "drain" and then plug it up with another valve?

Your stem should look like the this and with it at the top take it apart and change the whole valve core assemble...

CH3 comes with 9200# and is commonly available. You should be able to swap it out.

Just be aware that the upper component called CH3 has two different styles.

Peter 315 has the correct answer. I just went through the same process as stbill. I have Rimguard from 2011 in my DK35SE with industrial tires. I noticed a small leak between the tire and rim and figured the pressure was low. I tried to add air and the stem's core let go similar to stbill's experience. I tried the other tire and the same thing happened. I was able to jam the stem cores back in so did not lose too much Rimguard.

I had the tire service truck out and they changed to the proper stem Peter 315 suggests. They had to pump the Rimguard into a barrel. They pumped it so it collapsed the tire on the rim, then broke it loose and installed the proper, larger stems, and reinflated the tire. It took a couple of hours to pump the Rimguard out of the two tires because the original, improper stem is so small and the Rimguard was thick in the -5C weather. With the larger new stems it took only about 15 minutes for each tire to get the Rimguard back in. Including taxes the whole process cost about $350 cdn I believe. The whole process took 3.5 hours.

When I first installed Rimguard I asked the tire company(different than who did this repair) about proper valve stems because I heard the stems will let go. He assured me I had proper ones, and that was incorrect. I think the only solution is to use the stems Peter 315 suggests.

The problem is not Rimguard. The problem is some tire companys don't know what is required to install it. The tire company that repaired mine knew exactly what is required. You need proper METAL stems.

I still like Rimguard. We spilled quite a lot on the gravel floor of my shed, it made quite a mess, but that mess has more or less disappeared and posed no danger to pets or the environment.

If you have Rimguard with ordinary small rubber stems I recommend you arrange to replace the stems with proper ones before they fail, That way you can avoid doing it as an emergency in bad weather like I did.

Using liquid fill tire valves does not eliminate valve degradation from Rim Guard. Rim Guard is most definitely problematic in this regard.

I see what you mean by replacing 9200# in CH3. Is it a rubber component in that part that fails?

At least a failure of that component looks easy enough so even a non-mechanic like me can manage it. A failure of that part appears that it would be a very small leak as opposed to the gushing leak when the entire core lets go with the rubber stems. From his description it looks like the OP has rubber stems like I had.

I still like Rimguard for its relative safety compared to antifreeze options and non-corrosive properties compared to calcium chloride. My two previous tractors had significant rim damage from calcium chloride.

From Rim Guards site..Can I use rubber valve stems with Beet Juice Ballast?

It is important when installing liquid tire ballast that you consult a tire professional to ensure that you have industry standard valve stems capable of handling air AND liquid. Many rubber valve stems are air only and therefore the adhesive holding the core in place is subject to dissolving. This can potentially lead to a catastrophic failure and loss of all liquid in the tire.
