All great input guys, I really appreciate everyone's input. The tires are trash so I have no vested interest in keeping them in good shape.
At the moment I'm leaning towards the sawsall or maybe a 4 1/2" grinder. I doubt any of the tires are still maintaining their beads. I'll update in a few days as I came home with a new project. Here's a pic of my new shelving project for my TuffShed. I think there may be "some" assembly required. LOL
Carmadelle....welcome to Garage Journal, and hope you hang around. For what it's worth, and the time and effort, for a couple of bucks, take them to a tire place or WallyWorld and have them popped off. A few minutes, and you are done. Take the old tires with you so you don't have to pay a fee for disposal, unless you don't mind dropping an extra $10 or so for disposal.
And just for future reference, and to keep from getting blasted by many, and there was a CL or FleaBay thread about it........the word of the day is
Sawzall with a "Z", or to really cover bases...."reciprocating saw". When people see the word saw-saw, they get up, get dressed, and start looking through the toolboxes for the long breaker bars, pliers, and hammers to proceed to give someone a thrashing.
Show some of your projects, AND garage when you get a chance. Any toys, such as cars and or bikes? If so, post the pics, as we all very much like pics on here.
Pet peeves, my friend.....pet peeves

As far as making a hose reel out of a motorcycle wheel. is the rim wide enough to do that? I would think for maybe a 25' piece it may be alright, but I wouldn't think you could get a 50' length on there, unless it was a wide rear wheel.
Show it off as I know many would be interested in it.
