Chinese rims ruining inner tube stems?

[ETD66SS]

Well if you know the difference and it is not your first rodeo, I am stumped as well.

Where is Newfane NY? I know where Newfane VT is.

I will buy another glue on valve stem and put the tube on the rim without the tire and air it up. Not sure what else to do, don't want to buy another tube.

Newfane NY is about 30 miles east of Niagara Falls.

Ok. I spent most of my first 59 years in and around the Hudson Valley. Good luck with your tires.

It sounds like your tire is spinning on the rim. If so the diameter of the wheel might be too small. I'm not sure if anything you will do can fix this. It could be that they were made in a plant that uses metric and it's a close conversion to imperial. Or they could have just made them too small. It's possible the tire rubber is getting hard and more slippery.

I agree, and if the bead of the tire is shot, the tire could be spinning on the rim and then taking the tube along with it and tearing out the stem.

There is still rim manufacturing in the US. About Us - Titan International
My brother works at one of their plants.

Issue is, the stems get ripped off before we even drive the tractor. Now, I do think it is possible the tires can spin on the rims because there was so much rust on the beads from the calcium loading I may have taken too much rubber off with a wire wheel, but as said, the stems rip off before I get a chance to fire up the tractor and drive it.

I did some tests today. Pulled the tire off the rim, put an old tube on and filled it with air the best I could as it has a torn off valve stem. Now, the tube off center quite a bit, just wondering when the tire is on, is the tire bead yanking the tube away from the hole in the rim and tearing the stem?

The valve stem hole in the tube lines up fine with the hole in the rim:

Here is the part number stamped on the rim, not sure if this gives any indication where it is manufactured:

Some guys over at Yesterday's Tractor are blaming the rim, stating that some rims are for tubless use only and the stem hole on the rim is at such an angle it tears the tube valve stem. Are rims for tubless only really a thing??? If so I never knew that...

I finally got around to replacing the valve stem on the tube that was in this tire, I see no issues with the hole location in the rim, looks to me like there is plenty of room for the tire bead.

Your rim has no serrations. The bead surface on an ag wheel should be serrated to keep the tire from slipping on the wheel under tractive force. If the picture I tried attaching shows, you can see the serrations intended to prevent wheel slip. Some tractor pullers even run screws through the rims into the tires to prevent slippage. Slipping tires will quickly rip a tube stem.

OK, a couple of thoughts;
as has been mentioned there are no serrations on the rim to hold the tire and prevent rim to tire slippage under use.
However as the stems are getting pulled off prior to moving that lets that off the hook for now.

Looking at your pictures I see two things;
one the valve stem hole is very square and sharp, maybe dress that with a file a bit.
Also, when you had the tube lightly inflated on the rim it had a small pucker on valve stem side of the tube like it was being pulled,
also the tube is not centering in the rim.
If this continues to create issues I would patch the existing valve stem hole and moving several inch away add another hole in the
tube a couple of inches further up on the tube so it will center more evenly on the rim.

Good luck,

P.S. some bead sealer applied may help prevent rim slippage.

rims for tubeless tires have a much larger hole for the valve stem to be installed in the rim.. tubes don't need the large hole.. I would say your valve stem is not aligning up properly with the hole in the rim..
