Tire repair progress

super99 · Nov 27, 2020

I went to town this morning and got a piece of 3//16” tube at Napa. Came home and drilled through an old valve stem and stuck the tube inside it.

Took out the valve stem and screwed the one with the tube in and put some air in the tire and it was slow, but after adding more air a couple more times I got all but about a gallon out of the tire. Started breaking the tire down. Got one side done and started on the back side. They are 8 ply and fighting me all the way. Had to move the bead breaker 4 times to get the outside broke down. I expect getting it off of the rim will be a challenge!!!

My experience is larger tires are easier to dismount than small tires. Are they actually 8 ply or "8 ply rated"?
Soap, soap and more soap. How long are your tire irons? I would think 3' long handles would be a minimum. Push comes to shove, slide a piece of pipe over the handles.
Make sure to start near the valve stem at the same time forcing the bead at 180* down into the drop center of the rim. Mountng is just the reverse.

And get your self some Murphy’s soap to mount it.

If you let the tire down some,so there is pressure to keep it in the drop of the rim. It will pry off easier since you don't have to hold that and try to pry also. It also will combat the gravity for you. After you have it off part way then raise it up to hang and gravity will help there too. Reverse for putting on. Murphy oil soap or mounting compound will help with both directions. A vise grip on the rim lip will help with mounting to keep the bead from sliding around the rim as you pry. The guy that did the grain cart use 2 of them to hold it till he had enough to keep it on while prying the next bite on. That was a 12 ply tire.
