Hello. I was wondering if any of you have cast your own tires (say for scale planes if you cannot find the right size and pattern of tires available). I don't have any questions/problems with the mold-making itself but I am stumped as to what to use for the rubber? Some sort of RTV? What do the r/c car manufacturers use for their tires?

I am also concerned about the wear properties of the tires once done. I'd like something that can have some life to it and take a fair amount of taxying and landings and take-offs of a heavy bird. Thanks.
