Default Tyre Moulds

I have looked into doing moulds here in New Zealand. The cost was NZ$5750 for the mould for local pattern wheels with an insert in the mould for another NZ$1450 so that English / Canadian could be cast from the same mould.
Original English wheels seem to test out at 75 Shore hardness on average.
I was looking at using Black coloured polyurethane elastomer with mechanical properties as good, if not exceeding the original rubber. This project still sits in the melting pot! There is also on going research into the casting of tracks in China, but I do not see this happening any time soon.
