Mark and Kim, A word of warning on using old car tyres, while it is a great recycling idea there is a fair bit of evidence around to suggest that they leach cadmium, which you don't really want to be digesting. Also I think that cadmium can become quite concentrated in potatoes, so it's kind of a double whammy. If you are using the mounding technique with straw and compost it should be enough to make a wire mesh border to hold everything in and then you can just dismantle it and use it next year.
