At my local MTB trail there is a hill that was too steep for too long for me to do with a Duro Leopard tire though I tried many times. I don't have brakes and every time I got near stalling the tire would lose traction and I could never recover (allowing more tire movement always resulted in uncontrollable speed). The first dozen times I tried it with the IRC Kujo DH 24x3 I had success each and every time. Yes riding on pavement it is sluggish with its large footprint, but I have never wished for more turning ability on it off-road and can even do angled turns without the tire folding on me thanks to the pinch flat resistant sidewalls. The picture below is the downhill and another rider giving it a gallant go with a 26x3 Gazz...
