I have been sticking with the Kenda Parker DT for the last few years. They changed their tread patter last year. I liked it better before when it had more spacing between the center knob. Acted more like a paddle tire and since I do most of my riding in the desert, I liked the traction it provided. Still like the newer one over the others I've tried which is why I have stuck with them. Just adjust the tire pressure a bit depending on location of ride. Like Bid D, Ultra HD all the time :-)
