If your racing then the Panther Pythons are the BEST tire for the Revo on the Wabah wheel. We also narrow them by .25inch on the inside by cutting the bead off to the outside of the lip on the inner bead channel. The other side we remove one of the ridges so the lip on the Python Tire sits flat. Its a little mor work but they are super hooked up try them and you'll love them.
