Well did a run on grass dirt and black top the tires do pretty well have some wear from the black top but that's to be excepted since they are hard they grip will on grass and the dirt Hill I climb I think the best part of these are the fact that I have zero ballooning even running 6s so I'm happy. only bad I can see is that they don't slide like the stock tires and I end up rolling over now but I can adjust to that. The rest seems well the new motor didn't miss a beat and everything seems good so far except for the shock covers sliding down witch I kinda excepted
