I noticed the rear right tire appears to be low and there is some liquid leakage coming from the wheel and drooling on the tire. It is not a constant stream but there is a damp area on the inner and outer sides of the tire. The tire looks to be in good shape.
I am guessing it is a liquid tire weight. What do I need to do to fix it and how much is this going to cost me?
With basement work on our old house, replacing a cracked water heater and all the downstairs carpet from the water heater flood in our current house, helping our daughter and husband with a down payment for a house and getting ready to replace a tranny in a 1985 Chev pickup I am getting a little touchy about money. I guess I will hold off on the tranny because the tractor is more important.

I was in the tire business for twenty + years. If is almost Impossiable to give you a good figure for fixing your tire. You wi!ll need to have the fluid removed and reinstalled. It may be as simple as a split seam on your old tube. In that case you will need a new tube. If the tire if broken inside, you may need a boot or a new tire. If you've got a nail or a thorn it might just need a patch on your tube. Please get it fixed asap. If you run it low for any length of time you might pull the chords loose inside the tire. If that happens you will need a new tire.. Do not take the tire off the tractor and take it to a tire shop to get it fixed. It is far easier, safer, and quicker for a tire pro to fix the tire while it is still mounted on the tractor. Good luck with her.

In my case the tube was dry and replaced. Cost $300. This was an 18.4-38

Have you checked the valve to see if that's where the leak is coming from. Good idea to replace the valve every couple years when filled with fluid.

My experience has been that it is usually the valve stem. Check to see if that is where your leak is. If it is in that area, change the valve stem core. Easy to do and not expensive. Jack the tire up off the ground. Rotate the tire so the stem it at the top. Screw out the old core and screw in the new core. May need a couple pair of pliers to get the old one loose without damaging the outside of the stem. Save the old core, as the inside can easily be replaced with a new (not sure of proper name) inside thingy with the spring on it. Then you always have a replacement for next time you need it (which I have due to having multiple tractors with fluid in the tires). Dave

In any case I would suggest taking the tire off and cleaning the rim. If it is calcium chloride in the tire, it will eat the rim up if you don't get it cleaned off. If you have a mobile tire repair service nearby, have them come by and pump the tire out and break it down for you. Wash the rim, over and over again, inside and out. And then clean it a couple more times. Get a new tube and have the tire guy come back to put it back together and refill it.
If you don't need loaded tires, when the tire guy comes out the first time have him pump out both rears and sell it to him. I had two 28" pumped out and it cost me $35 since they kept the juice.
You may want to get two tubes and have both rears done. If they are original tubes and don't appear to have had any work done on them, then the other one will probably go down as soon as you get the first one done. Two tubes don't cost that much.

I agree with John!
It is a cheap fix now. Waiting until the rim has rotted away is going to cost you MUCH more money!

Thank you all for your responses. Sounds like I better get on this one pretty darned quick. We are 20 miles from McPherson, 20 miles from Hutchinson and 20 miles from Lyons so there are shops in our area. I'll look for a small business first but if there is not one available I will go with a big dealer. The valve core is shot but it is stuck inside the stem and breaking apart.
The Chevy pickup can wait a few months

Yes it is a FACT that with calcium filled tires it is not IF they will leak, but WHEN. the best thing you can do is drive out back by the fencerow with some nasty weeds and remove the valve stems and use the solution for weed killer. Also it is a lot cheaper to have air only tires worked on.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Well, I do have some poison hemlock trying to make a comeback in a small area. When we bought our property the hemlock had taken over a wide area between the sheds, near several stands of trees and along fence lines. Those weeds have got to be tired of looking at that orange tractor so I'll be happy to give them their last look.

I work in a Calcium Chloride plant. Contained in a vessel in this case a tire tube it is harmless on a surface that is exposed it will rust things out. HD6Tom said lots of good ideas. Call your tire guy today get him out and repair it. While he has it apart wash it up well with HOT HOT HOT water if it’s uncomfortable to hold onto the garden hose that’s about the right temp. HOT water dissolves it the best. In the plant we have 75 plus year old equipment in the “wet” end.
Edited to add: At home in the past I hooked a hose to the drain on the hot water heater.
