I do not know of anyone that has tried using tires as papercrete forms. Especially as a permenant form.
The biggest problem I see is that even with holes drilled in the tires for drainage, the rubber still would probably cover most of the papercrete and slow the water evaporation process dramatically, nearly to a standstill. As spaceman mentioned, cutting off a sidewall might allow someone to use them as a temporary form. Place tire, pour, allow for initial drainage, pull off, move to next one. I guess if someone wanted short cylindrical papercrete block, this might be reasonably effective.
If you want typical rectangular shapes, I think other methods of making forms make a lot more sense.
Also, drilling holes in tires can be done, but cutting up a tire is not easy. Try it sometime with an old one. Those round buggers are TOUGH! That is why they are so effective in earth and rubble foundations.
If you are looking for extra cheap material (perhaps free) to make slip forms, you might try experimenting with used pallets. Those can often be gotten for free. You can use a reciprocating saw to cut through the nails holding them together if you want the individual pieces of wood. You also might be able to use the pallets whole as part of a slipform. Of course, you'd need to add more wood to block up the gaps between the slats. Cutting up another pallet should provide the wood to do that.
It might take a little experimentation to glue/screw all the small piece together to make the size of form you desire, but that is the price you pay when you are looking to pinch pennies. At least you'd be building your forms out of recycled materials.
You also might want to keep your eyes open for construction and demolition sites. They often throw out debris that can be reused for all kinds of things. Most (but not all) will allow someone to dig through their dumpster. It can save them money on dumping fees. Less stuff to haul away.
Keep that creative thinking hat on.

Or does anybody have any ideas for a simple, cheap slipform? We are really wanting to get something out on the land this summer for a sturdy, semi-permanent shelter for the fence building week. All ideas are welcome. Thanks!
