Another flat tire ...advise sought

onefarmer · Oct 18, 2020

I've been having rear tire issues off and on for years on my JD4430. They seem to be going flat for no reason. I was having the tire store do the fixing but that got expensive. So now doing it myself.

On the tires that were on it original, lasted for years and then started in going flat. After 3-4 repairs I got mad and put new tires on figuring a belt came loose and was rubbing a hole on the tube. That worked for awhile now the new tires are doing it. I check for nails, thorns, and holes in the tire and never find any. I event check the rim and nothing. I put in a new tube and they last for a year and they go flat again.

I even added more air so they wouldn't wrinkle under a hard pull. I don't use this tractor only for heavier field work. It's not like a daily driver.

What brand of tube are you using? We found that the Firestone's have been holding up the best for us in the pulling tractors.

Original was Firestone, went to Titan, now on the dual I'm using an off brand I got from ebay. That one hasn't gone flat yet.

The originals I moved out to the duals when I put the Titans on. They still were going flat. At least there wasn't fluid to fuss with.

I run duals most all the time. I would think if I was overloading it, the in furrow tire would have gone flat after I plowed down sod this spring. But the left is the flat one and after I put the dual back on

Good tubes are hard to get the best is a tube for a log skider but the price is a killer

Don't overlook a bad valve core, it's an inexpensive thing to fix. Metal valve caps with the rubber seal can also help reduce pressure lose from a leaky core.

It's not been a bad core yet. I air up the tube every time to track the leak and it's always had a small hole. But no corresponding nail or puncture in the tire.

I go tubeless whenever possible, but if you can't go tubeless then I have made a liner out of an old tube. Either split it around the inside diameter or the outside depending where you are having the problem with the tube. If the tires have ran with to low of psi the cords could be bad sometime that's hard to detect.

Where are the leaks when you find them? If it is always a small hole in the tube, are checking the tire for a nail or thorn, in the same place? Are you marking the tire in relation to the tube-so you know where the tire and tube were when they were together so you can match the hole in the tube to the tire? Are you making sure that there is no dirt, gravel, or debris left in the tire before you install the tube that could rub a hole in the tube? I always run a rag on the inside of the tire to feel for sharp, pointy things that would poke the tube-the rag will snag on on it. Mark.

We had a rear tire that would go flat a couple of times a year. It did not matter if a tire shop fixed it or I fixed it. New tubes made no difference nor if it was loaded or not. New tire and tube this spring and we have had no problems with it since

Sounds very familiar. Just like when I replaced the originals. Now it's starting all over again. I'm ready to change the rim too. Or go with radials

JD Dave · Oct 18, 2020

Do not overlook rust and abrasive materials on the inside of the rim when using a tube. I've found that some of the smallest debris inside the tire or on the rim can cause ruined tubes.

If your using a bias tube a small piece of dirt will ok rub a hole in them, bias tubes are thinner than they use to be And are pretty much junk today
Ive been using the thicker radial tubes and the only flats Ive had were on a set of Michelins with cracking side walls
