So the right rear tire isn't holding air so figure I will break it down and install a replacement inner tube. Who has these that are of good quality ?
Thanks in advance

It’s been a few years but when I needed rear inner tubes, a local tire store sold me Firestone tubes. They were much thicker than the tubes carried by TSC and such places. You might go to your local tire dealer and pose the same question. Ask the professionals, so to speak.

If your local dealer doesn’t have one in stock, he should be able to get one in.
you will find that all of them are made in chimna, korea, and other east asia countries and it not gonna matter what name is stamped on them. All of them have a high plastic content mixed in and even the thick ones are not like they used to be, ---- they crack when they get hot out in the sun just like the tires weather check.
I salvaged an old thick one for the 2444 last year. so far its holding so if you have a thick one --- patch it up-- dont replace it!

Ok folks thank you all for this input. I am heading out now to a local shop near me that does AG farm tractor tires so I will see what he says. I went through a couple of sets of front tubes, then realizing I needed better stuff and they now seem to be holding up better. I got this Cub nearly 18 years ago with what were then nearly new rear tires with tubes. I don't know what tubes are in there, but I figure its best to use the best I can get. I don't put many hours on this machine per year so that 18 years isn't so great, but time also can be a factor.
I agree with Gary D. I buy tubes from a local dealer that sells Firestone's. While they are made in China they must spec them to be a heavier tube.
Hi,
The tube might only be having a problem with the valve leaking, and you don't need a new tube.
The rubber in the valve core can get hard and not seal after years.
You didn't say if you checked the valve for leaking. The valve core can leak, or other parts of the valve can leak. The valve core might not be tightened firmly and leak. Check it's tightness.
If it is tight, and leaks, push it down and let it up a few times, there could be some small dirt stuck in it.
If it won't stop leaking, I would go to NAPA or other automotive parts store and buy a new valve core, and replace that, inflate the tire to 12 lbs or more, up to the maximum pressure recommended for the tire, and see if it leaks. If it was a slow leak, let it sit and check it with a tire pressure gauge some.
The air pressure will probably go down 1 or 2 lbs in the tire, when the air in it first cools. It is probably warm from the compressor.
You need a tool to install or remove the valve core. The end of metal valve caps have the tool. The valve core screws into the valve.
The original rear tractor tubes have a round nut that screws onto threads, and holds the valve onto the rim. They have a replaceable valve stem that goes into the base of the stem, the base of the stem is made on the tube.
Below are pictures.
Pic 1 is a valve core.
Pic 2 are metal caps with the tool for the core. NAPA sells those also, I think.
Pic 3 is the replaceable part of the valve stem. That is the older style that years of Cubs came with.
There is a newer style that your tubes may have, if they are 18 years old.
Pic 4 shows the round nut holding the valve in the rim.
Maybe you knew all this before.

Before buying anything, I would inflate the tire/tube and check the valve. You don't need to buy a new valve first. If you put a new valve in without checking the old one first, you won't know if you actually fixed the problem. Check the old valve first so you can rule that out.
Hi,
12 psi for the rear tires is what the earlier Cub owner's manuals said to use. It works ok if you don't have weight on the drawbar that you are lifting.
The 1965 Cub operator's manual has more of a range of tire pressures you can choose from.
Below is the page with the rear tire pressures. The 9.5" x 24" tires don't use as much maximum pressure as the 8.3" x 24" tires.

Yes, you could put more than 12 lbs in the rear tires to check for a leak.
Below is the page with the front tire pressures. If you have an implement on the front, like the Cub 54 Blade, when it is in the front position, more air pressure in the front tires can help it steer easier. You probably need tires in good condition to use the higher pressures.
