Kenda's K-Rad is a true multi tasker. Ride to the skatepark and bang off a session, then hit the dirt jumps in the afternoon. Hit the vert ramps then do an urban assault on it, the K-Rad is down. The inverted tread design gives you a fast, smooth ride on the street, without sacrificing anything when the pavement ends and you hit the dirt. The knurled tread and traction bars in between the knobs keep the tire from deforming, whether you're leaning into a turn on the street or railing the pump track.
