The left rear tire on our Case 841 needs to be removed to work on the valve stem hole. It is a 18.4 X34 inch setup. Would like to remove the tire from the rim while leaving the wheel center and rim on the tractor. Could you help me out by letting me know what techniques you use to break the bead of the tire free from the rim ? Also, is there a fluid that can be applied to the tire bead rim interface that will help ? Anything to watch out for ? Have not done this before.
I really appreciate you help. Many Thanks !
 
Back in the 50s, I worked in a country town service station and we also fixed tractor tires---often rusted up from calcium chloride. Our main tool was a curved wedge with a sliding hammer. Since then I have used a lot of tricks to get tires off without special tools. I eventually bought a tool called the bead cheta.

You are going to need a pair or tire irons or a pair of very large screw drivers to remove the tire after the beads are broken. If you Google IMAGES OF TIRE BEAD BREAKERS, you will see a large variety of tools used to break beads. Some are inexpensive.

With two tire irons, a three pound hammer, a hefty screw driver, and a dozen flat washers for a 1 inch bolt, this might work for you.

First, hammer the two irons into the bead-rim interface about 5 inches apart and as far in as they will go.

Second, use the hefty screwdriver to pry between between the two irons to create a gap wide enough that you can insert, or hammer in, a washer into the gap.

Third, remove one of the irons and hammer it in 5 inches on the other side of the iron still engaged.

Fourth, repeat step two and insert a second washer

Fifth, repeat the above until you have about six washers inserted. This creates an 1/8 inch gap about 2 feet long.

Sixth, repeat the above except hammer the irons in at the inserted washers and insert double washers into the gap created. You should now have a 1/4 inch gap about 20 inches long.

Seventh, repeat the above extending the length of the gap from 20 inches to about 40 inches more or less.

At this point, you can probably hold and hammer the iron at 45 degrees and finish breaking the bead.

For a fluid to lubricate the interface, brake fluid or WD 40 should work well.
 
Farmerhr get yourself some NAPA brand bead lube or something similar. Use plenty A duck billed tire hammer will break down the outside bead. Take your 2 30" tire irons, pull the outside bead over the rim, start with your valve stem up and use the 2 tire irons to pull the tire up over the bead, this will keep you from shearing the stem off the tube. This will give you a couple of inches more room to work on the inside bead. 2-12" tire irons driven between the rim and tire on the inside, about 6 inched apart, will give you enough room to start your wedge on the inside bead. once the inside bead is broken slide the tire out pull your tube. don't bother using dish soap for lube. It ISNT slick enough. This is how I did it for 22+ years. good luck, I found 18.4X38's easier to do than the 34" stuff.
 
A mattock can be used to break the bead down. I think it is easier to take the tire off with the wheel on the tractor, gravity can be your best friend if you do it right. Amazon sells many bead lubricants. Doing a YouTube search for tractor tire removal would be helpful too.
 
RonSa has given you some really good advise. So I hope he doesnt mind me adding to it. What you need are 2 tire irons like ken tool 33238. These tire irons are 30" long and 7/8" diameter. You really want the 30 in irons. To break the bead you can either have a duckbill tire hammer or a Bead Breaking/ Driving Iron like Ken Tool 3216. Add in a 3 lb hammer and a good pair of heavy vise grips and your ready.

list;

2 - Ken tool 33238 tire irons

1 - Ken Tool 3216 Bead dreaking Driving iron

1 - 3 lb short handled Sledge hammer

1 - Vise Grips

If you want to save money its is possible to buy tire irons from Northern Tool but the will break under heavy use. The Ken Tools are what you need to change a heavy bead tractor tire like an 18.4 x 34
 
I think they have covered every trick in the book. I sure they all work but it's probably still not going to be fun

If you've never done this before or seen it done, it might be worth your $$$ to hire someone to break it down for you, show you how to check the rim, tire and tube and show you how to put it all back together. It's not hard to learn, but it can be hard to accomplish if you don't know what you're doing. If you happen to have a rim that's rusted solid to the tire...a 16 lbs sledge or the outrigger from a backhoe may be required to bust it loose.
 
The DIY approach here in Scotland would be to cut to pieces of 2 inch angle bar at about 4 inches in length, these would then be driven between the rim and the face of the tyre. Assuming the agle iron enges have been cleaned up and you are monitoring what is happening as you drive the angle iron further in should creat any damage. Keep in mind though that depending on how well your aim is and how heavy your hammer is the angle iron can fly off so best wear some PPE. Good luck.
