I am looking for a person who can cast me some resin tires that are soft. made out of something like Urethane. I can send you the tire itself, and can pay(not much at first) or trade. I got a couple things left but not much. I am looking to get a couple sets made, and want to mess around with them. If anyone can do something like that, please let me know. We can haggle over the details via PM.
