Tires Leaky tire

[bake321]

I have a slow leak in my right front tire on my M9540. Tried finding it with soap and water and had no luck, so I did what any country boy would do and drove into the creek. Turns out it is at a weld point on the rim. I'm thinking that taking off the tire and welding from the inside would br the best way to seal it. I could also check for a stress crack this way. Any one else have any ideas?

Why not use an innertube?

I thought of that, but would like to be able to plug it in the future if needed.

most likely you end up having to buy a new rim.

Is there a reason not to repair the failed weld like by grinding out the crack and rewelding? Was it a bad weld. I know a person who had a leaking combine rim due to a weld crack. He tubed it and later that year suffered what he called the loudest bang he thought possible when the rim split completely and it blew. Of course 9 ton of grain in the bin of a 12 ton combine puts a lot more load through the rim than your tractor does but there is still a lot of energy in the compressed air in the tire. You really need to make sure the split doesn't progress and not just do only what is needed to keep air in the tire.

an that rim could also bust the hub when blows out as well.

I'd weld it then grind it smooth and give it a squirt of paint (just in case you want to use a tube someday).

Well here's an update. I went out to the tractor and both front wheels were flat. Put air in them and headed back down to the creek. The second one has the same leak which is actually at the one of the rivets that holds the bracket in place where the wheel center bolts to the rim. This morning I pulled both wheels and took the tires off of the rims. These are 12.4R24 and I was proud that the old man could do it the old manual way. At the leak points I could see where the rivet head had shifted. I also noticed a couple of others where the paint had chipped from stress. I am going to seperate the wheel centers from the rim, clean all the rivet heads and clean next to the brackets on the outside and weld everything with my wire feed. This Is a 90hp tractor and I dug out my pond with it. I guess that stressed the rivets. When I get done they will be better than original. I noticed that my neighbors New Holland was welded from the factory. I guess Kubota was trying to save money.

I had the same problem. Talked with the dealer and going I was not the first. The problem was the light rims with a loader and front wheel assist. Too much strain on the rivits. It was still under warranty so I was able to return these and upgrade to the heavy rims for just the upgraded cost. No problems since then.
