I didn't take pictures but my problem looked a lot like ncampbell's MF mess.
It was very cold here this winter and I went through my firewood much faster then anticipated. So, in early Feb I was uncovering a pile of logs in my yard so that I could cut and split them. While I was doing that I ended up being sideways to the slope of my yard and ended up getting deeper into the snow and the log pile !!@#$.
A log lodged into my rear tire and broke the valve stem. When I bought my tractor in the Michigan UP the rear tires came loaded with Rim Guard. Rim Guard is beet juice and it adds about 200 lbs per tire to help stabilize the tractor when using the loader. The air and Rim Guard leaked out. My tractor was buried in deep snow and I had a flat tire. I had to get the tractor unstuck and get the tire remounted and filled with Rim Guard.
Fortunately it isn't too far from my house. It was a mess though. The rear right tire was pretty much off the rim but still had the v-bar chain on it. I tried using a come-along and a snatch block yesterday but it wasn't moving.
The next day I went out and tried pull it out forwards by hooking a chain to the bucket hooks and use the snatch block and 100 feet of my new Samson 1/4" rope. I rigged it up and managed to easily pull it out with my truck; despite the slippery icy conditions. My wife watched and gave me directions as I inched the tractor out with the truck. We had to stop often and turn the front wheels on the tractor and a few times I thought it might tip but it only took about 40 minutes to pull it out in front of the house. If that didn't work I would have had to to get my neighbour over here with his skidder-that or a backhoe or maybe a tow truck.
Another lesson learned. Never let your tractor, or any vehicle, get sideways even on the slightest decline. I did something stupid like that two years winters ago but didn't get hung up as bad. I didn't have chains on the tires then. Now I have chains on the front and back tires and I still #$%^&* up .
The next day I had to load the still very heavy tire and rim into my truck and bring it over to Michigan to have it remounted and refilled with Rim Guard.
This could have been a disaster but it was all good. It cost me $160 for a tube, 20 gallons of RimGuard and remounting.
Getting that 300+lb tire and rim off my truck and back on to my tractor took some doing and patience but the job was much easier then I thought it would be.
