The Proline 2.2 Badlands wear really slow. I run em on my Evader and 80% they're slipping from excessive power and throwing stones/dust. I also do a lot of asphalt running, such as donuts, drifting, and speed runs. I've had them since last summer and probably won't need a new set until next spring. I've been very happy with them and they're plenty knobby.
