I finally have successfully molded and cast some tires . I thought I'd post how I did it as I have seen some queries in the past. I am doing them in regular resin not soft silicone. For my purposes this is fine.

Nice job.

 

I am curious- does anyone know if the resin or silicone tires will have the negative reactions like vinyl tires do with styrene?

 

It's a question that's passed through my mind recently, and this posed a good opportunity to ask.

If you use a medical or food grade silicone, it should be completely unreactive with anything when cured. Proper mixing ratio is critical.

 

Engineering-grade hard resins should also be unreactive if mixed and cured properly. With catalyzed materials, there <should> be no leaching out of plasticizers like there is with vinyl, which is what causes the problem.

No, urethane resins, once cured, do not attack styrene.
