People do often make their own wheels and stick rubber (often bike tyre screwed on). It might be worth making hubs for these RC car tyres but most RC car tyres are quite small (I think... are they about 50mm diameter max?). The compounds of RC car tyres will probably perform quite/very well but robustness of the whole wheel is a key issue.

I think there is a feather called Electric Blue (or something like that) which uses 4 wheels from RC monster trucks, I cant remember if they used custom hubs but the wheels certainly looked grippy.
