Quite good! Specially on mudd, grass and gravel these Tires performs very well. But not on the street because of the harder rubber of this tires. The main thing is taken theses adapters. I use 4 x front wheels from the HPI Baja. The rear wheels where too wide for the Big Rock and also too much weight / wheel. One more positiv point: These wheels has beadlock rims and there is much less ballooning of the tires.
