I would pick kevlar over steel. Lighter and more pliable for how it needs to be used. But fiberglass would be a good choice as well. I vote yest because anything would be helpful to tone down ballooning. I also think maybe a foam tire pre-mounted on light dish wheels with an applied rubber tread would be interesting as well.

Whatever may come about, there is a lot of room for improvement. Although I will say RC tires have come along way over the last 10 years too.
