I build 1/24 scale models for clients from pictures of "the one they
wish they still had" Right now I am building a Pro Street 2006 Camaro Station
Wagon! Chevy made one up to the clay stage and then dropped the prototype program for it. A engineer asked me if I could build him one. I found a resin s/w body on ebay. $9.99 My point is I have a guy who casts tires for me when I need. I would be more than happy to ask him for tires anyone needs. You have the buck built which is the most difficult part. He also can use different compounds to fit the application.
MicroMark sells a good rubber mold compound for use in silicone molds. You
would be able to make a 2 part mold using the correct mold release spray.
Any questions, please ask. Joe
Experience is what you get right after you needed it.
